From the Interfax report:

“I learned about the incident from TV. My opinion is: the special services have framed my children, because they are practicing Muslims. Why did they kill Tamerlan? He was supposed to be caught alive. The younger is on the run now. He was a sophomore at a medical school in the U.S. We expected him to come home for vacation. Now I don’t know what’s going to happen. Tell you once again: I believe special services have framed my children.”

Reports on Twitter also claim that Anzor has said that “all hell will break loose,” if his remaining son, who is currently on the run in a suburb of Boston, is killed.

The AP reports that the father of the suspects also spoke with their own reporters. During a short conversation Anzor Tsarnaev was said to have told the reporters that his children were ‘true angels’.  He also said that he has two more daughters who live in New York.
