Russia has reportedly declined to provide the FBI with information about one of the Boston marathon bombing suspects two years before the 2013 attack.
Dzhokhar Tsarnaev, a native of Russia's Chechnya region, is charged with killing three people and injuring 264 others when he and his brother planted two homemade bombs along the course of the Boston Marathon. Tsarnaev's brother Tamerlan was killed by police after the attack.
Citing an unpublished U.S. government review, "The New York Times" quoted on April 9 a senior U.S. official as saying, "They found that the Russians did not provide all the information that they had on [Dzhokhar] back then, and based on everything that was available, the FBI did all that it could."
The paper said U.S. lawmakers are to be briefed on April 10 on the report, authored by the inspector-general of the Office of the Intelligence Community.
