Anzor Tsarnaev, who calls himself father of Dzhokhar and Tamerlan Tsarnaev, the two suspects in the Boston Marathon bombings, gave an interview in Makhachkala, calling one of his sons an "angel."
"My son is a true angel," Anzor Tsarnaev said to the AP of his son Dzhokhar, who is still on the run.
"They were set up, they were set up!" he added. "I saw it on television; they killed my older son Tamerlan."
"I'm scared for my boy - that they will shoot him dead too," said the thin man in a black-and-blue sweater. "They should arrest him, bring him in, alive. And the judicial system should investigate everything, who's right and who's guilty."
Tsarnaev also said he was expecting the younger brother to visit him in Dagestan soon for summer holidays, before cutting the interview short.
It was not possible to independently verify he was the brothers' father, but he has also been identified as such in Russian and other media reports.
The two suspects in the Boston Marathon bombings are ethnic Chechen brothers who spent much of their lives away from the breakaway Russian republic and showed few signs of radicalism in the United States, friends and relatives said.
