WASHINGTON – The CIA pushed to have one of the suspected Boston Marathon bombers placed on a U.S. counterterrorism watch list more than a year before the attacks, U.S. officials said Wednesday.
Russian authorities contacted the CIA in fall 2011 and raised concerns that Tamerlan Tsarnaev, who was killed last week in a confrontation with police, was seen as an increasingly radical Islamist who could be planning to travel overseas.
The CIA request led the National Counterterrorism Center to add Tsarnaev's name to a database known as the Terrorist Identities Datamart Environment, or TIDE, that is used to feed information to other lists, including the FBI's main terrorist screening database.
The CIA's request came months after the FBI had closed a preliminary inquiry into Tsarnaev after getting a similar warning from Russian state security, according to officials who spoke on condition of anonymity.
The disclosure of the CIA's involvement suggests that the U.S. government may have had more reason than it has previously acknowledged to scrutinize Tsarnaev in the months leading up to the bombings in Boston. It also raises questions as to why U.S. authorities didn't flag his return to the United States and investigate him further after a seven-month trip he took to Russia last year.
The CIA declined to comment on its role in the case. A U.S. intelligence official said that the agency had "nominated Tsarnaev for inclusion in the watchlisting system" and had shared all of the information it had been given by Russia, including "two possible dates of birth, his name and a possible variant."
The official said that the information that Russia provided to the CIA was "nearly identical" to what it had shared with the FBI. U.S. officials said the warning to the CIA came from Russia's FSB, a successor to the KGB, and that it was based on fears that Tsarnaev was an Islamist militant who might seek to carry out a terrorist attack in Russia.
Tsarnaev and his brother, Dzhokhar, 19, immigrated to the United States about a decade ago, but their family had ties to Chechnya, a region where Muslim separatists have been engaged in a conflict with the Moscow government for decades. The younger Tsarnaev, who is recovering from gunshot injuries in a Boston hospital, was apprehended days after the marathon bombings and faces multiple terrorism-related charges.
