MAKHACHKALA, Russia — The parents of the two brothers accused in the bomb attack that killed three people and wounded more than 260 near the finish line of the Boston Marathon insisted on Thursday that their sons were innocent and had no connection to radical Islam.
In an outpouring of anguish and anger at a news conference here in the capital of Dagestan, the brothers’ father, Anzor Tsarnaev, and mother, Zubeidat Tsarnaeva, also made accusations of a conspiracy in which the American authorities murdered their older son, Tamerlan, after seizing him.
Officials in the United States have said that Tamerlan was shot during a wild standoff with the police and was run over by a car driven by his younger brother as he escaped from the scene. The younger brother, Dzhokhar Tsarnaev, was captured and has been charged with using a weapon of mass destruction. He is recovering in a Boston hospital and may face the death penalty if convicted. Officials have also released video showing the brothers near the site of the marathon bombing.
Despite this evidence, and after two days of questioning by agents of the Federal Bureau of Investigation here, Ms. Tsarnaeva said she would not accept that her sons were guilty.
“No I don’t — and I won’t,” she snapped at the news conference. “Never!”
