The father of suspected Boston Marathon bomber Dzhokhar Tsarnaev has called on his son to surrender, but warned the U.S. that “all hell will break loose” if he is killed. Anzor Tsarnaev spoke to ABC News from his home in Russia, while his younger son dodged bullets during a gunfight with Boston police late Thursday night. Tamerlan Tsarnaev, the elder of the two brothers suspected in the marathon attack, was killed in a shootout. Their father said he spoke to both on the phone earlier this week and insisted they were innocent, but asked his younger son to stop running. “Give up,” he said via ABC News. “You have a bright future ahead of you. Come home to Russia.” Meanwhile, an uncle of the two boys has called them “barbarians,” saying they “don’t deserve to live on this earth.”
