 At least two Palestinians have been killed and 200 wounded in the West Bank during protests against Israel's campaign in Gaza, officials say. 
 
 About 10,000 protesters marched from Ramallah towards East Jerusalem, where they were met by Israeli forces. 
 
 At least 15 people died and scores were injured when a UN-run shelter came under fire in Gaza on Thursday. 
 
 More than 800 Palestinians and 35 Israelis have died since the Israel-Hamas conflict began on 8 July. 
 
 Palestinian leaders in the West Bank have called for a "day of anger" on Friday, one of the last days of Ramadan. 
 
 The protest at Qalandia, outside Ramallah, saw Israeli border police use "riot control measures" and live fire. Protesters also used live ammunition, Israel said. 
 
 Large protests were also reported in Jerusalem on Thursday evening, after Israeli police prevented men under 50 from visiting the al-Aqsa mosque. 
 
 At least 20 protesters were arrested after they threw rocks at police, Israeli police said. 
 
 Israel launched its military offensive with the declared objective of stopping Hamas firing rockets into Israel. 
 
 It has since discovered a network of tunnels used by militants to infiltrate Israeli territory, and has vowed to destroy them to restore security. 
 
 Efforts to broker a ceasefire have been continuing despite the continued violence. 
 
 Reports suggest a deal under discussion could allow Israeli forces to remain in Gaza to destroy tunnels.

 Palestinian leaders say this is the start of the "uprising of freedom and independence". Thousands marched from the outskirts of Ramallah towards the Qalandia checkpoint calling for an end to the Israeli occupation. 
 
 Youths threw stones and petrol bombs towards the checkpoint and tried to destroy the barrier. I heard the sound of rubber bullets and occasional live fire. Israeli police say they used sound bombs and tear gas. 
 
 The demonstration was called for by a group of youths on Facebook, among them the son of the popular imprisoned Fatah leader Marwan Barghouti. Palestinian President Mahmoud Abbas has urged Palestinians to expand the protests, and leaders in the West Bank have called for a "day of anger" on Friday. 
 
 Gaza school: Pools of blood

 It was the fourth time in as many days that a UN facility has been hit. 
 
 Correspondents say pools of blood lay on the ground in the courtyard of the school in Beit Hanoun, and there was a large scorch mark where it appeared a shell had hit. 
 
 Secretary General Ban Ki-moon condemned the strike, and UN officials said that during the course of the day they had been trying to negotiate a window of time with the Israeli army for civilians to leave the area because of the heavy fighting. 
 
 Chris Gunness, a spokesman for the UN Relief and Works Agency for Palestine refugees (Unrwa), said the Israeli army had been formally given the co-ordinates of the shelter in Beit Hanoun. 
 
 According to the UN, more than 118,000 people are now sheltering in UN schools and people are running out of food. 
 
 Lt Col Peter Lerner, a spokesman for the Israel Defense Forces (IDF), did not admit responsibility for the attack on the school. 
 
 "We do not target the UN. We do not target civilians. There was no target in the school. Gunmen were attacking soldiers near the facility. The school was not a target in any way." 
 
 Israeli PM Benjamin Netanyahu said on Thursday he regretted each Palestinian civilian death, but said they were "the responsibility of Hamas".

 Hamas leader Khaled Meshaal told the BBC he wants a ceasefire and end to Israel's blockade as soon as possible. 
 
 "We don't want to be controlled by a border crossing that makes Gaza the biggest prison in the world," Mr Meshaal, who lives in exile in Qatar, told BBC Hardtalk. 
 
 "People cannot go for medical treatment or to work. Why are the people of Gaza being punished by a slow death in the world biggest prison? This is a crime."

 The UN's Office for the Coordination of Humanitarian Affairs (Ocha) says a 3km (1.9 mile) wide strip, encompassing 44% of Gaza, has been designated as a no-go zone by the Israeli military since the current conflict began. 
 
 Israel imposed restrictions on the Gaza Strip in 2006, after Hamas abducted Israeli soldier Gilad Shalit. 
 
 The measures were tightened by Israel and Egypt in 2007, after Hamas ousted rival Fatah and forcibly took control in Gaza after winning elections the year before. 
 
 Hamas and Fatah announced a reconciliation deal in April, but the move was condemned by Israel - which regards Hamas as a terrorist group. ||||| JERUSALEM (AP) — Israeli aircraft struck 30 houses in the Gaza Strip early Friday, killing a leader of the militant Islamic Jihad group and two of his sons, while ground troops and Hamas gunmen fought intense battles in the north and center of the territory, Palestinian officials said.

 The Israeli military confirmed dozens of sites were hit, including what it said were Hamas command posts, but did not elaborate. 
 
 With the current round of fighting entering its 18th day, Israel's Security Cabinet was to meet later Friday to decide whether to expand its operation or consider ideas for a cease-fire. 
 
 One plan calls for a five-day humanitarian truce during which Israel and Hamas would negotiate new border arrangements for blockaded Gaza, said Hana Amireh, a senior Palestine Liberation Organization official in the West Bank, who is involved in cease-fire efforts. 
 
 Hamas has said it will not halt fire without international guarantees that Egypt and Israel will open Gaza's border crossings and end their seven-year-old border blockade. Israel and Egypt are reluctant to ease the blockade, fearing this will enable Hamas to tighten its grip on Gaza. 
 
 Israeli media reported that the military also wants more time to continue destroying rocket sites and tunnels from Gaza into Israel that Hamas has used to launch attacks. The military has found 31 tunnels but only destroyed about one-third of them so far. 
 
 In Jerusalem, meanwhile, thousands of Israeli security forces were deployed for possible Palestinian protests after Friday prayers at a key Muslim holy site, said police spokeswoman Luba Samri. 
 
 The night before, thousands of Palestinians protesting the Gaza fighting clashed with Israeli soldiers in the West Bank. One Palestinian was killed and dozens were wounded, according to Palestinian medical officials. 
 
 In Gaza, the death toll soared to 808, after 115 Palestinians were killed on Thursday in one of the deadliest days of fighting, said Ashraf al-Kidra, a Palestinian health official. Thirty-four Israelis, among them 32 soldiers, and a Thai worker have been killed since July 8. 
 
 Early Friday, Israeli warplanes struck 30 houses throughout the Gaza Strip, including the home of Salah Hassanein, a leader of the military wing of Islamic Jihad, the second-largest militant group in Gaza after Hamas. 
 
 Hassanein and two of his sons were killed in the strike, said Gaza police spokesman Ayman Batniji and al-Kidra. 
 
 Over the past two weeks, Israeli aircraft have repeatedly hit homes of Hamas and Islamic Jihad leaders. Most had gone into hiding, but the strikes killed a leader of an Islamic Jihad rocket squad, a Hamas commander and a son of senior Hamas leader Khalil al-Haya, according to the Israeli military. 
 
 Such strikes have also claimed the lives of a large number of civilians. A Gaza human rights group said earlier this week that close to 500 homes have been damaged or destroyed in direct hits from the air, and that more than 320 people have been killed in their homes as a result of military strikes.

 Associated Press writer Karin Laub in Gaza City, Gaza Strip contributed to this report. ||||| Palestinian Authority calls for 'day of rage' after women and children are killed by Israeli shelling while seeking shelter 
 
 The violence of the conflict in Gaza spread to the West Bank on Thursday with at least two Palestinians killed and scores wounded in one of the biggest clashes seen for several years. 
 
 
 
 Further protests in the West Bank and East Jerusalem are expected following noon prayers on Friday, the last Friday of Ramadan, after the Palestinian Authority called for a “day of rage” over the bloodshed in Gaza. 
 
 Thousands of Palestinians took part in a demonstration after more than 15 women, children and United Nations staff were killed and around 200 injured when a UN shelter for those fleeing the Israeli bombing was hit. 
 
 The Israel Defence Forces insisted it had given the occupants of the shelter time to leave before shelling the area. But the UN flatly contradicted that, saying it had made repeated attempts to negotiate a window during which people could safely leave the area but none was granted. It said it had given the IDF precise co-ordinates of the location of the school. 
 
 Meanwhile reports emerged that the US secretary of state, John Kerry, had presented both sides with a new proposal for a cessation of violence. It centred around a week-long temporary ceasefire with Israeli troops allowed to stay in Gaza to locate and destroy tunnels; and simultaneous negotiations for a permanent deal, with guarantees by the US, EU and UN that the primary concerns of each side would be addressed. 
 
 Kerry was said to be awaiting a response from Israel and Hamas before leaving Cairo to return to Washington later on Friday. Israel's security cabinet was due to meet later on Friday to discuss the plan. It will also discuss the option of expanding its eight-day-old ground operation in Gaza. 
 
 Hamas's leader-in-exile, Khaled Mishal, said a truce must include a guaranteed end to Israel's eight-year blockade of the Gaza Strip. "We want a ceasefire as soon as possible, that's parallel with the lifting of the siege of Gaza," he told the BBC. 
 
 The school in Beit Hanoun in the north of Gaza was one of the grimmest incidents of the conflict, now in its 18th day and in which more than 800 Palestinians – mostly civilians – have been killed. Thirty-four Israelis and one Thai worker have died. 
 
 Ban Ki-moon, secretary general of the UN, condemned the shelter attack, which came hours after the agency had warned that Israel's actions in the Palestinian enclave could constitute war crimes. "Today's attack underscores the imperative for the killing to stop and to stop now," Ban said. 
 
 Valerie Amos, the UN's top humanitarian official, described the attack on the school as “appalling”. 
 
 The school was hit while its playground was crowded with families waiting to be ferried to safety. According to survivors one shell landed in the schoolyard followed by several more rounds that hit the upper storeys of the building. 
 
 Most of the wounded were moved initially to a local hospital where terrified women and children clung to each other, waiting for news of relatives. A shell exploded about 50 metres from the hospital building as they waited. 
 
 Following the attack a trail of bloody footprints could be seen crossing the deserted playground, which was littered with abandoned possessions. There were pools of blood both inside and outside the school building; more blood was splashed over wooden school desks. 
 
 Nour Hamid, 17, said: "We were packing up to leave when the attack happened. We were standing outside when they started hitting us, some of the women holding their babies. My sister-in-law was one of the injured. There were bodies everywhere, most of them women and children." 
 
 
 
 Laila al-Shinbari told Reuters: "All of us sat in one place when suddenly four shells landed on our heads … Bodies were on the ground, [there was] blood and screams. My son is dead and all my relatives are wounded including my other kids." 
 
 Ayman Hamdan, medical director at Beit Hanoun hospital, told the Guardian that medical staff were treating multiple shrapnel injuries and damage to internal organs. "Some of the bodies were blown apart. Such a massacre requires more than one hospital to deal with it," she said. 
 
 More than 140,000 Palestinians have sought shelter in UN premises during the conflict. Several schools run by UNRWA, the UN agency for Palestinian refugees, have come under fire in the last week. On Tuesday a school in Maghazi, central Gaza, sheltering about 1,000 people, was hit by Israeli shells as an UNRWA team inspected damage caused by an earlier strike. 
 
 
 
 Thursday's strike occurred during a day of heavy fighting across the territory as Israel pressed ahead with its operation to halt rocket fire from Gaza and destroy a sophisticated network of cross-border tunnels. 
 
 The Israeli military, which said it was "reviewing the incident", claimed the incident had occurred during "heavy combat" in the area and accused "terrorists" of "using civilian infrastructure and international symbols as human shields". 
 
 
 
 Facebook Twitter Pinterest Protests take place in the West Bank against Israel's onslaught in Gaza. 
 
 In the West Bank clashes between the IDF and up to 10,000 people demonstrating against the Gaza offensive erupted in the volatile area around the massive Qalandiya checkpoint between Jerusalem and the West Bank city of Ramallah. 
 
 The IDF said it used "riot dispersal means" – a term used to cover weapons such as rubber bullets and tear gas – against protesters, who threw rocks and molotov cocktails at them and blocked a road with burning tyres. It did not say whether live rounds had been used. 
 
 According to Israel Radio the protest appeared to be the largest since the Palestinian second intifada, or uprising, which ended in 2005. 
 
 Two other Palestinians have been killed in confrontations in the West Bank this week. On Thursday night police also clashed with Palestinian protesters around Jerusalem's Old City.
– The West Bank erupted in violence last night after one of the biggest protests in years ended in clashes between Israeli forces and people marching in solidarity with Gaza. At least two Palestinians were killed and 200 wounded as Israeli border forces used riot control measures and live ammunition against thousands of demonstrators, reports the BBC. The Palestinian Authority has called for a "day of rage" over Israel's Gaza offensive and more clashes are expected today. Yesterday's demonstration took place after at least 15 people were killed and up to 200 injured when an Israeli strike hit a United Nations school sheltering people fleeing Israeli bombing. The Israeli military says it gave people the chance to leave before shelling began, but the UN denies that, saying it tried and failed to negotiate a window of time during which people could safely leave, the Guardian reports. John Kerry has come up with a two-stage plan to end the fighting in Gaza, an official involved in negotiations tells the New York Times. The first step would involve a weeklong truce beginning on Sunday, during which Israeli, Palestinian, and international negotiators would discuss issues affecting Gaza. But negotiations are at a delicate stage, the official says, and issues like an Israeli demand to keep its troops in Gaza during the truce are still being discussed. Yesterday was one of the bloodiest days of the 18-day-old conflict, with 115 Palestinians dead bringing the total to more than 800, the AP reports. Some 34 Israelis, including 32 soldiers, have been killed. Early today, Israel hit at least 30 sites in Gaza, killing a leader of the Islamic Jihad group and two of his sons, and ground troops clashed with Hamas militants.
