Anzor Tsarnaev, Father of Suspect 2, Says "All Hell Will Break Loose" if Son Dies

From ABC:

The father of suspected Boston Marathon bomber called on his son today to give up peacefully, but warned the U.S. that if his son is killed "all hell will break loose."

Anzor Tsarnaev spoke to ABC News from his home in the Russian city of Makhachkala as Boston police carried out an intense dragnet for his son Dzhokhar Tsarnaev.

Dzhokhar Tsarnaev, 19, survived a running gun battle with police during the night that left an MIT security officer dead and a Boston cop badly wounded. His older brother died in the shootout.

The father said he spoke to his sons by phone earlier this week. "We talked about the bombing. I was worried about then," Anzor Tsarnaev said.

He said his sons reassured him, saying, "Everything is good, Daddy. Everything is very good."
