[EX Q]: The mayor of the eastern Ukrainian city of Kharkiv underwent emergency surgery after being shot in the back, city officials and police said Monday, amid continuing unrest in the region. The attack on Mayor Gennady Kernes happened around noon local time, the Kharkiv city office official website said. It was not immediately clear who was responsible for the shooting. After a two-hour operation, Kernes was out of surgery but in critical condition, the city office said. "The surgery was successful. His life-threatening condition is expected to go on for several days," a statement said. "He was unconscious when brought to the hospital." The online statement also said a bullet casing was found at the scene. Police said an investigation unit was trying to determine the circumstances of the shooting. In a major challenge to Kiev's new leaders, armed rebels have captured towns and government buildings across eastern Ukraine and are holding a team of European monitors hostage. Western nations accuse Moscow of supporting the separatist gunmen who are occupying official buildings in cities across the region. Sanctions . The United States on Monday imposed sanctions against seven Russian government officials and 17 companies linked to Russian President Vladimir Putin in its latest action to punish Moscow for its actions in Ukraine. The White House said the seven Russians, including two from Putin's inner circle, are now subject to a freeze on any assets they hold in the United States and a ban on U.S. travel. In addition, the United States will deny export license applications for any high-technology items that could contribute to Russian military capabilities. The Commerce and State departments will revoke any existing export licenses that meet these conditions, the White House said in a statement. "The sanctions build on the ones that were already in place. We're moving forward with an expanded list of individuals," U.S. President Barack Obama earlier told reporters in Manila, Philippines. The move, Obama said, was to spur Putin to "walk the walk, not just talk the talk" in resolving the crisis in Ukraine. If the latest round of sanctions does not work, the next phase could target economic sectors like banking, Obama said. The European Union also announced Monday that it was imposing sanctions on 15 people who are "responsible for actions which undermine or threaten the territorial integrity, sovereignty and independence of Ukraine." A list of the people targeted by the latest sanctions will be published Tuesday and will go into effect at the same time, the Council of the European Union said. The sanctions will include asset freezes and travel bans. U.S. and Russian defense secretaries speak . U.S. Defense Secretary Chuck Hagel spoke on the phone with Russian Defense Minister Sergei Shoigu on Monday. According to a Pentagon description of their conversation, Shoigu "reiterated his assurance that Russian forces would not invade Ukraine." Hagel, the Pengaton said, called for an end to what he described as "Russia's destabilizing influence inside Ukraine" and "warned that continued aggression would further isolate Russia and result in more diplomatic and economic pressure." The Russian government's description of the call said Shoigu "definitively denied the groundless allegations of the presence of Russian sabotage and military intelligence groups on Ukrainian territory" and criticized what he called "anti-Russian hysteria recently unleashed in the Western press." He also criticized what he said was an "unprecedented" increase in activity of U.S. and NATO troops in Eastern Europe near the Russian border, according to the Russian government's description of the call. Ukrainian soldier killed . A homemade bomb exploded near Ukrainian soldiers who were in the eastern Donetsk region Monday, killing one and injuring another, Ukraine's Defense Ministry said. The death came days after Ukrainian forces said they killed five pro-Russian militants in an operation to clear roadblocks near the city of Slavyansk last week. Police are investigating Monday's blast, the Defense Ministry said. A CNN team covering a pro-Ukraine rally in Donetsk watched violence unfold Monday as pro-Russian separatists wielding batons beat demonstrators who said they wanted to see a united Ukraine. Observer freed . Pro-Russian separatists holding a European military observer team in eastern Ukraine released one of the observers for medical reasons Sunday, shortly after parading them before cameras. At least seven of the inspectors from the Organization for Security and Co-operation in Europe appeared at a news conference staged by Vyacheslav Ponomarev, the self-declared mayor of Slavyansk, who referred to them as "prisoners of war." The freed observer was from Sweden and had been suffering from diabetes, Ponomarev spokeswoman Stella Khorosheva told CNN. Michael Bociurkiw, an OSCE spokesman in Kiev, called it "a welcome development." The monitors were seized Friday outside Slavyansk, one of the flashpoints in the standoff between Ukraine's interim government and pro-Russian factions challenging its authority in the east. They said that although they have diplomatic status, they went along with Sunday's news conference because the mayor asked them to. Germany strongly criticized the group's appearance before the media. The "parading of OSCE observers and Ukrainian security forces as prisoners is abhorrent and a flagrant violation of their human dignity," Foreign Minister Frank-Walter Steinmeier said in a statement. He added that Russia had a duty to "influence" the separatists so that the other members of the mission could be freed as soon as possible. Putin has repeatedly criticized what he says is Kiev's use of force against Ukrainian civilians.

[EX Q]: The discovery of a slain Palestinian teen in Jerusalem early Wednesday further inflamed tensions in a region already unsettled over the killings of three Israeli teens, not to mention decades of entrenched enmity between all sides. Mohammad Abu Khedair, 17, was heading from his home to a mosque in the middle-class neighborhood of Shuafat for prayers around 4 a.m. when three men forced him into a car and drove off, his father, Hussain Abu Khedair, told CNN. His body was found about an hour later at a forest in Jerusalem. The killing quickly triggered condemnations from Palestinian and Israeli leaders, as well as from the United States. Abducted Palestinian teen was kind, beloved . Those who spoke out passionately included an uncle of one of the three Israeli teens whose bodies were found earlier this week. He called the young Palestinian's killing "a forbidden action, and it has no forgiveness." "Any act of revenge of any kind whatsoever is completely inappropriate and wrong. Murder is murder," said Yishai Frankel, uncle of Naftali Frankel, a 16-year-old dual Israeli-American citizen, to Israel's Channel 2. "One should not differentiate between bloods, be it Arab or Jew. Israeli authorities are probing Wednesday's death, with police spokesman Micky Rosenfeld tweeting this effort will try to determine if it is a "criminal or nationalistic" act -- the latter term referring to a politically motivated act in retaliation for the Israeli  teens' killings. Mark Regev, a spokesman for Prime Minister Benjamin Netanyahu, told CNN late Wednesday that investigators "at this stage cannot say who did this killing." This came hours after Netanyahu's office promised a speedy investigation to find "who is behind this despicable murder and the background to this act," according to a statement from his office. "Netanyahu calls on all sides not to take the law into their own hands. Israel is a country of law and everyone is ordered to act according to the law." The killing riled many Palestinians, particularly in Jerusalem. But it didn't happen in isolation. Israelis and Palestinians continue to trade blows -- over longstanding issues unrelated to Abu Khedair's death -- through rocket attacks and airstrikes. All this violence, from various angles, leads to one big question: When will it stop? Report: Body was 'charred and bore signs of violence' "Settlers" kidnapped the teenager and his body "was charred and bore signs of violence," according to the Palestinian state news agency WAFA. DNA, through saliva samples, was used to positively identify the boy, his father said. Rosenfeld told the Jerusalem Post the teen had significant burn marks. The same Israeli publication also reported police are looking into previous kidnap attempts on members of the teenager's family related to a personal dispute. Yet Hussain Abu Khedair, the boy's father, blamed Israelis and vehemently denied reports that this may have been tied to any sort of family dispute. "Netanyahu is responsible for the crime," the father told CNN, "because he is the one who is giving the settlers the cover and supporting them." The teen's cousin, Majdi Abu Khedair, said whoever carried out the abduction was driving a car that had been used in an attempted abduction two days ago. A similar claim was made to Haaretz by Knesset member Ahmed Tibi. The cousin passionately suggested: "The Israeli police and Israeli government should do the same as they have done in Hebron: Demolish and blow the settler houses who have done this crime." The Israeli military destroyed the homes of the two suspects in the killings of the three Israeli teens. When confronted with this suggestion, Regev insisted "we are totally color blind when it comes to this sort of criminal act." "There's no difference between a Jewish resident of Jerusalem or an Arab resident of Jerusalem," the spokesman said. "... Police will get to the bottom of this." "It is sickening to think of an innocent 17-year-old boy snatched off the streets and his life stolen from him and his family," said Secretary of State of John Kerry, who talked with Netanyahu by phone about the situation. "There are no words to convey adequately our condolences to the Palestinian people." He noted that both Israeli and Palestinian officials have condemned it, and he added to Netanyahu's call. "Those who undertake acts of vengeance only destabilize an already explosive and emotional situation." Palestinian Authority President Mahmoud Abbas, who heads the Fatah party and is based in the West Bank, called Mohammad Abu Khedair's father and promised that those behind his abduction and death will be brought to justice, WAFA, the Palestinian state news agency, reported. And Hamas -- the militant Islamic organization that controls Gaza -- said in a statement that it holds the "Israeli occupation (fully) responsible," adding that the incident "exposes (Israel's) ugly ... racism" and "refutes the Israeli narration of being the victim all the time." Anger, clashes in Palestinian neighborhoods of Jerusalem . As news of the boy's death spread, public anger in Palestinian neighborhoods of Jerusalem rose to levels rarely, if ever, seen since the Second Intifada, or uprising, last decade. That led to several clashes around the city, the biggest of which was centered in Shuafat. Residents there threw stones at security forces and the Israeli authorities responded with occasional volleys of stun grenades or tear gas. Some protesters attacked two Palestinians whom they mistook for undercover Israeli police, The Jerusalem Post reported. The clashes expanded and continued through midnight in the Palestinian neighborhood, with a large amount of Israeli forces on hand. In Suwwaneh, Palestinians threw rocks at a nearby settlement and several of them were injured by rubber bullets, witnesses said. And some tossed Molotov cocktails at an Israel settlement in Silwan, outside Jerusalem's Old City. The Palestinian Red Crescent Society reported that more than 100 were injured, most of them in Shuafat, in the clashes. There were concerns that the Palestinian teenager's funeral could spark further unrest. But his father said Thursday he was still waiting to hear from Israeli authorities when the body would be handed over to the family. "The autopsy should be done around 1 p.m., and then I am supposed to wait for a call," Hussain Abu Khedair said on Palestinian television. "We will not bury my son at night," he said. "We will do it during the day. If they purposely delay, we will do it during the day even (if that means) tomorrow." Israeli airstrikes into Gaza . Meanwhile, the dangerous back-and-forth between Gaza and Israel was erupting yet again. Rockets from the Palestinian territory into Israel was met by at least eight airstrikes within about an hour early Thursday. Three hit a Hamas intelligence building in Gaza city, while at least one struck the Qassam training camp in Beit Hanoun. Palestinian medical sources reported at least 10 injured, one of them seriously. Israel Defense Forces said the airstrikes -- going after 15 Hamas targets -- were in response to the firing of more than 20 rockets into Israel since Wednesday. This is in addition to other actions -- including the arrests of hundreds of Hamas activists, the demolition of homes and the closure of dozens of institutions in Gaza, according to Netanyahu -- targeting Hamas and focused in Gaza. This action follows the abduction of Israeli teens Eyal Yifrach, Gilad Shaar and Naftali Frankel as they were on their way home from school June 13; the three were found dead on Monday in a West Bank field. Hamas praised the kidnappings but denied that it was responsible for what happened. It warned that if Netanyahu "brings a war on Gaza, the gates of hell will open to him." At the teens' funerals, Netanyahu said the country would avenge their deaths at "the hands of evil men." "A broad moral gulf separates us from our enemies," he said. "They sanctify death; we sanctify life. They sanctify cruelty and we mercy and compassion. That is the secret of our strength." Opinion: Teens' killing hurts Israelis, bad for Palestinians .

[EX Q]: London (CNN) -- Internet giants signed up Tuesday to a "zero tolerance" approach to images of child sexual abuse as the British government announced a new, tougher strategy to find and block illegal content. Google, Yahoo, Microsoft, Twitter and Facebook were among the firms summoned to a meeting on the issue at 10 Downing Street, the prime minister's residence, by the UK government's Department for Culture, Media and Sport. The summit was called in the wake of two recent UK child murder cases. In each case, the killer had viewed child sexual abuse images and violent pornography on the Internet, sparking calls for action to eradicate such content and protect vulnerable young people. After the summit, the government said the Internet Watch Foundation -- a watchdog body set up in 1996 -- would have new powers to seek out child sex abuse images, block access to them and remove them. The watchdog has previously acted after an image of child sexual abuse was reported to it via a hotline. While there are an estimated 1 million unique images of child abuse online, only 40,000 reports are made to the Internet Watch Foundation each year, the Department for Culture, Media and Sport said. Now, the watchdog will work with a cross-agency government body, the Child Exploitation and Online Protection Centre, known as CEOP, to hunt down such images, the department said. And the UK's leading Internet service providers -- Virgin Media, BSkyB, BT and TalkTalk -- have agreed to give Â£1 million ($1.57 million) over the next four years to help fund the new approach. Tuesday's agreement represents a "fundamental change" in the way child sexual abuse content will be tackled, the Department of Culture, Media and Sport said. "This will mean more images of child sexual abuse will be tracked down and acted on," said Culture Secretary Maria Miller. "The abuse of children is absolutely abhorrent -- and that child is further violated every single time an image is circulated and viewed. The IWF and CEOP already do important and valuable work. "This agreement will mean these organizations will no longer be limited to reacting to reports received. They will now have the remit and the resources to take the fight to the criminals perpetrating these vile acts." In addition, Internet providers have agreed to introduce by the end of the month special pages to tell users when they try to access a page that has been blocked by the Internet Watch Foundation. The four main UK Internet service providers will also beef up the parental control options they offer, so that parents can easily restrict Internet access on all devices in their home by the end of the year. The main cell phone service providers in the United Kingdom also took part in the talks. All the firms present signed a statement saying: "We have a zero tolerance approach to the presence of child sexual abuse material on the Internet." Prime Minister David Cameron, speaking to reporters at the Group of Eight summit in Northern Ireland, said he was "personally committed" to the battle. He said he welcomed steps to make sure the big Internet companies "use their expertise, their brains and their brilliance to get these disgusting images off the Internet much faster." Tuesday's summit is not the only action taken by Web giants to tackle the scourge of exploitative images online. Google said Tuesday that it will spend $5 million on an effort to wipe pictures of child sexual abuse from the Web and another $2 million to research more effective ways to find, report and eradicate the images. Some of that money will go to the National Center for Missing and Exploited Children as well as the Internet Watch Foundation, said Jacqueline Fuller, the director of Google Giving, in a blog post. The Web giant also is creating the Child Protection Technology Fund to develop more efficient ways to fight child porn, and already works to tag illegal images and prevent them being found elsewhere.
