Mother Of Boston Bombing Suspects Tamerlan and Dzhokhar Tsarvaev Says They're Innocent; Zubeidat Tsarnaeva Says She Regrets Moving Family To U.S.

Zubeidat Tsarnaeva, the mother of Boston bombing suspects Tamerlan and Dzhokhar Tsarnaev, spoke publicly for the first time at a press conference in southern Russia and said she regretted moving her family to the U.S. Tamerlan was killed in a shootout with police last weekend, while Dzhokhar remains in critical condition at a Boston hospital and is still unable to speak.

"Why did I even go there? America took my kids away from me," she said. "What have you done to my son? Why did they have to kill him?"

Tsarnaeva was adamant that Tamerlan was alive when police arrested him and claimed he died later in custody, something that both the Boston Police Department and FBI deny. She believes that her children were set up in a political conspiracy, but declined to give further details.

"Politics is a dirty game, not everyone can speak about this. I do not know who needed this. I know one thing, this has been done and that it was not my children," she told reporters. "Everything that has been said does not match our children."

Their father, Anzor Tsarnaev, said he would travel to the U.S. today and visit his one remaining son. Tsarnaeva said she wished to join him on the trip, but was concerned about being allowed into the country due to a previous shoplifting charge. Tsarnaeva also added that she was thinking about relinquishing her U.S. citizenship.

An official told The Associated Press on condition of anonymity that both Dzhokhar and his parents are continuing to be interviewed, declaring that the investigation "is ongoing, it's not over." While questioned in the hospital, Dzhokhar said that he and his brother were not part of any militant group and that they were self-taught and self-radicalized.

Prosecutors are seeking the death penalty for Dzhokhar for his role in the bombing. Five deaths and 299 people injured have been reported from the bombing so far.
