Update 12:16 a.m.: In an impromptu conference with reporters, Tsarnaev uncle Ruslan Tsarni implored Dzhokhar to "turn [himself] in and ask for forgiveness."

Update 11:25 a.m.: A second uncle of the Tsarnaev brothers, named Alvi Tsarni, has come forward. In an interview with CBS, Tsarni revealed that he spoke to Tamerlan Tsarnaev on the phone yesterday. “Yesterday he called me and said ‘forgive me,’” Alvi Tsarni said.

Tsarni also expressed disbelief that his nephews committed the bombings. “I’m sorry too if he did this. It’s crazy… It’s not possible… I cannot believe he did this,” he told CBS.

Update 10:38 a.m.: In an interview with ABC News, the father of Boston Marathon bombing suspect Dzhokhar Tsarnaev claims that he will urge his son to "surrender peacefully," but warned that "all hell will break lose" if he is slain by police.

Family members of Tamerlan and Dzhokhar Tsarnaev have allegedly spoken out about the two Boston Marathon bombing suspects.

In an interview with CBS Boston affiliate WBZ-TV, Ruslan Tsarni, the uncle of the two brothers, revealed that the alleged bombers immigrated to the United States around 2000 or 2001, and have lived in Cambridge, Mass., ever since.

Tsarni told WBZ-TV that Dzhokhar graduated from a Cambridge-area high school and subsequently attended college somewhere near Boston.

The Tsarnaev brothers’ uncle had strong words about his two nephews. He described Tamerlan as a “loser,” and claims that he was shocked when he heard about the shootout that left Tamerlan dead and Dzhokhar on the run.

“He deserved this. He absolutely deserved this,” Tsarni told WBZ-TV. “They do not deserve to live on this earth.”

The Tsarnaevs’ father did not share Tsarni’s harsh views on the bombing suspects. In a phone interview with the Associated Press, Anzor Tsarnaev, who lives in Makhachkala, Russia, referred to the at-large Dzhokhar Tsarnaev as a “smart and accomplished” individual.

"My son is a true angel," the elder Tsarnaev told AP. "Dzhokhar is a second-year medical student in the U.S. He is such an intelligent boy. We expected him to come on holidays here."
