WASHINGTON (CNN) -- Russian military aircraft flew just 500 feet over two U.S. Navy ships this week as the ships participated in a joint military exercise with South Korea in the Sea of Japan, according to U.S. military officials. Two Russian Ilyushin IL-38 maritime patrol aircraft flew only 500 feet above a U.S. aircraft carrier. On Monday, two Russian Ilyushin IL-38 maritime patrol aircraft, known as "Mays," overflew the U.S. aircraft carrier Stennis while it was in international waters in the Sea of Japan. The Russian aircraft flew about 500 feet over the ship, lower than other flights the Russians have made over U.S. ships in the past year. The USS Stennis was about 80 miles east of Pohang, South Korea, participating in the joint military exercise when the flyover occurred. On Tuesday, the USS Blue Ridge, a lead command and control ship, and the Stennis were overflown by two Russian "Bear" long-range bombers multiple times, according to U.S. military officials. The Bears overflew the ships at about 2,000 feet, officials said. U.S. military officials said that in both cases, U.S. Navy F/A-18 fighters met up with the Russian aircraft about 70 nautical miles from the U.S. ships and flew alongside them until they left the area. On both days, U.S. aircraft tried contacting the Russian planes on international air frequency radio channels, but the Russian pilots did not respond, officials said. The last time Russian planes flew over a U.S. Navy ship was February 2008, when two Bears flew 2,000 feet over the aircraft carrier USS Nimitz south of Japan. Russian long-range flights skirting U.S. or other nations' boundaries have also been common over the last year. Although the Pentagon does not often talk about the overflights, there is nothing illegal about the actions, and they are generally seen by the United States as nothing more than muscle-flexing by the Russian military.

(CNN) -- A Nevada man was found guilty Thursday of raping and strangling a 19-year-old student in a string of attacks that rattled the university community in Reno two years ago. A Washoe County, Nevada, jury convicted James Michael Biela, 28, of first-degree murder and sexual assault in the death of Brianna Denison. He was also convicted of two counts of sexual assault for attacks on two other women. He was also convicted of one count of kidnapping related to one of those attacks. The father and former construction worker faces the death penalty. Denison, a sophomore at Santa Barbara City College in California, was last seen alive on her friend's couch on January 20, 2008. Three weeks later, her body was found in a field near her friend's home. She had been sexually assaulted and strangled. A pair of panties that did not belong to Denison were found near the body, in what police said was a "calling card" that helped them connect Biela not only to Denison, but also to the other assaults. From the witness stand in Biela's capital murder trial, one of the women recounted how she was attacked on the University of Nevada-Reno campus. She said her assailant threatened her with a gun, raped her and took her panties as a souvenir. The defense challenged the identification because she earlier told a friend she could not describe her attacker to police. The second woman, a student at the university, testified she was abducted outside her apartment and driven to a dark area and raped in the attacker's vehicle. The woman testified that her assailant asked for her panties and took them with him. The trial began with emotional testimony from Denison's mother, her boyfriend, and a video showing her with friends at a diner just a few hours before she was abducted. Denison was visiting friends in her hometown of Reno. After they attended a concert, she slept on the living room couch in a friend's off-campus apartment. While she slept, someone crept into the apartment and snatched her, police and prosecutors said. Her case triggered a flurry of national media coverage and thousands of tips, including the one that led to Biela's arrest. Police released a photo of the panties near Denison's body and a description of the pickup truck. A friend of Biela's girlfriend saw the photo of the panties, and thought she recognized the truck police described. She told investigators a friend's boyfriend had a truck similar to the description, and that her friend had seen women's panties inside it. Detectives immediately followed up on the tip and, with permission from the girlfriend, took DNA samples from Biela's 4-year-old son. Lab tests showed that the boy's father -- Biela -- was almost certainly a match for the DNA found on the doorknob and at the crime scene, police said. DNA obtained from the other victim's rape kit matched Biela's, according to testimony. Biela's defense attorneys challenged the DNA testing method, claiming it was not accurate. CNN's Rupa Mikkilineni contributed to this report.

The gunman who held hostages for more than 16 hours in a Sydney cafe was no stranger to police -- and was on bail for violent criminal offenses at the time of the siege. Man Haron Monis, an Iranian-born refugee who was granted political asylum in Australia in 2001, had "a long history of violent crime, infatuation with extremism and mental instability," Australian Prime Minister Tony Abbott told reporters. "It's pretty obvious that the perpetrator was a deeply disturbed individual," he said at a press conference Tuesday, adding that the 50-year-old was "well known" to federal and state police, as well as the Australian Security Intelligence Organization. "But I don't believe he was on a terror watch list at this time." New South Wales Premier Mike Baird said authorities were investigating why Monis -- who was killed in the siege -- was at large, given his criminal background. "We're all outraged that this guy was on the street," he told reporters. "We need to understand why he was. We also need to understand why he wasn't picked up." What we know, what we don't know . Accessory to murder, sex charges . The self-styled Muslim cleric, also known as Sheikh Haron, was facing dozens of charges at the time of the siege, including two counts of being an accessory to the murder of his ex-wife, according to the Attorney General of New South Wales. Noleen Hayson Pal was found dead with multiple stab wounds in a stairwell, and her body had been set on fire, The Sydney Morning Herald reported. "They should have put him away and thrown away the key," the dead woman's godfather, Ayyut Khalik, told NBC News. He said Monis used to beat Pal, forcing her to wear a hijab all the time and forbidding her from talking to "outsiders." Court documents show Monis was also facing 45 sex-related charges, including sexual intercourse without consent and aggravated indecent assault. According to the Sydney Morning Herald, the initial charges, laid in May 2014, related to an alleged sexual assault on a woman in western Sydney in 2002, before other sex-related charges were added regarding six additional victims. Monis was using the name Mohammad Hassan Manteghi -- his birth name, according to Iran's state news agency IRNA -- and claimed to be a "healer," according to the report. Monis also pleaded guilty last year to writing offensive "poison pen" letters to the families of Australian soldiers who died in Afghanistan, and was sentenced to 300 hours of community service. The letters were "sadistic, wantonly cruel and deeply wounding," one High Court judge said at the time, according to CNN affiliate Seven News. But the criminal accusations against him began even before he came to Australia. Monis fled his homeland in 1995 while being sought for allegedly committing fraud, Iran's semi-official Fars News reported. A spokesperson at Iran's embassy in Canberra told CNN that Tehran had officially requested Monis's extradition but nothing had come of it. Monis had been granted political asylum in 2001 and had had no further contact with his birth country, the spokesperson said. Who were the victims? An extremist theology . Manny Conditsis, a lawyer who acted for Monis in relation to the accessory to murder and letter-writing charges, told CNN his former client had been a cleric in Shiite Iran, but had become critical of the Islamic Republic's government in the late 1990s, and fled to Australia "because he was going to be killed." He had left behind a wife and two children, who he believed Monis had not seen since. Throughout the 2000s, said Conditsis, Monis "became sympathetic to what he perceived ... was the victimization of Muslims and Islamists around the world, and partly at least took up that cause." His broader cause, he said, was lobbying governments around the world, particularly Australia, not to wage wars on Muslim soil. "He was so blinded by that objective that it would seem he had lost sight of objectivity and rationality and acted in extreme ways," he said, describing his former client as "intensely conflicted and contradicted and inconsistent." While older footage of Monis preaching shows him dressed in typical Shiite cleric's attire, in his social media posts, he appears to embrace a radical Sunni extremist theology. He used the Internet to spread extremist beliefs, garnering nearly 13,000 likes on his Facebook page. During the siege, Abbott said, the hostage-taker "sought to cloak his actions with the symbolism of the (ISIS) death cult," Abbott said. On his website, which has now been taken down, there was a pledge of allegiance to the so-called Islamic State terror group. The site describes Monis as a Muslim cleric and activist based in Sydney who has "continuously been under attack & false accusation by the Australian government & media since he started his political letter campaign from 2007." There's a graphic photo of slain children at the top of the site. Under the image, it reads, "This is an evidence for the terrorism of America and its allies including Australia. The result of their airstrikes." A description on the site portrayed Monis as a victim of a political vendetta and compares him to Julian Assange, the WikiLeaks founder who has claimed the sex crime allegations he faces are politically motivated. A YouTube video posted in November shows Monis standing on a street corner, chains draped over him, carrying a sign that says, "I have been tortured in prison for my political letters." Police have refused to comment on that accusation. His last tweet linked to his website, with a haunting message posted the day of his attack on the Sydney cafe: "If we stay silent towards the criminals we cannot have a peaceful society. The more you fight with crime, the more peaceful you are." Conditsis  told Australian public broadcaster ABC that Monis was an isolated figure who was probably acting alone. Crisis in a cafe . Monday's hostage situation began around 10 a.m. Hundreds of police officers, including snipers, took position around the Lindt Chocolate Cafe in Sydney's central business district. Australian media captured haunting images of hostages pressing their hands against the cafe's windows. They were reportedly taking turns holding a black flag with Arabic writing on it that said, "There is no God but God and Mohammed is the prophet of God." The man holding the hostages demanded to speak to Abbott. Police were monitoring social media because hostages appeared to be posting information about the man's demands. Hours into the crisis, at least five hostages managed to escape, running terrified toward police in riot gear. That made the hostage-taker furious, reported Chris Reason, a correspondent for CNN affiliate Seven Network. Reason said he could see the gunman become "extremely agitated" when he realized what had happened, and he "started screaming orders" at the remaining hostages. Gunfire erupted early Tuesday as police stormed the cafe where the gunman had been holding hostages. Two hostages were killed during the standoff. Police later announced that the siege was over and that the lone gunman had been killed.
