On Friday, the uncle of two brothers suspected of planting bombs at the Boston Marathon earlier this week called on his nephews to "turn yourself in, and ask forgiveness for your crimes."

During a press conference outside his Boston home, Ruslan Tsarni was asked by reporters what provoked nephews, Dzhokhar Tsarnaev and Tamerlan Tsarnaev, into carrying out the bombings.

"Being losers," Tsarni explained. "Hatred to those who were able to settle themselves. These are the only reasons I can imagine of. Anything else to do with religion, with Islam, it's a fraud, it's a fake."

Tsarni described the brothers as Muslims who were ethic Chechnyans, and speculated that the young men could have been "radicalized" by someone outside the family.

The uncle insisted that he "loved this country" because it "gives chance to everybody else to be a human being."

Tamerlan Tsarnaev was reportedly killed in a firefight Thursday night, but Tsarni had a message for Dzhokhar Tsarnaev, who police were searching for on Friday.

"If you're alive, turn yourself in!" he exclaimed. "And ask for forgiveness from the victims, from the injured and from those who [survived], ask for forgiveness from these people! We're not requiring forgiveness in this family. He put a shame on our family, Tsarni family. He put a shame on the entire Chechnyans ethnicity! Because everyone now names, now play with the word Chechnyan. So, they put that shame on the entire ethnicity!"

"Those who suffered, we're sharing with them with their grief. I'm ready just to meet with them, I'm ready just to bend in front of them, to kneel in front of them, seeking that forgiveness."
