(CBS News) Several family members of the Boston Marathon bombing suspects -- identified as Dzhokhar A. Tsarnaev, 19, of Cambridge, Mass., and Tamerlan Tsarnaev, 26 -- spoke out Friday morning, all expressing shock at their actions, but offered contrasting descriptions of the young brothers.

Two uncles -- Alvi and Ruslan Tsarni -- spoke to CBS News and CBS Boston affiliate WBZ respectively. Ruslan Tsarni said he was "absolutely shocked" and "absolutely devastated" upon hearing of his nephews' involvement in the attack and said it was "not comprehendible [sic] in our family."
"They've been refugees in this country. Refugees come from war," Ruslan said of their background, though he described the older brother, Tamerlan, as a "a loser."
He called his nephews "barbarians, wherever they are" and said after learning of their involvement in the bombings, "They do not deserve to be on this earth ... What can I say? They murdered."
Another man believed to be their uncle, Alvi Tsnarni, told CBS News has not been in touch with either brother since 2009 and believes their parents have moved back to Russia.
Alvi Tsarni told WBZ he learned of his nephews' involvement and Tamerlan's death on the news. "I can't believe this, it's not possible," Tsarni said, "My nephews can't do this stuff. There's no way."
Anzor Tsarnaev, the father of the suspects also spoke out from Russia on Friday morning, telling the Associated Press, "My son is a true angel. 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." The brothers are not students and Dzhokhar was not enrolled in medical school in the U.S.
