Months after the FBI cleared Tamerlan Tsarnaev in its investigation of possible connections to jihadist causes, the Russians approached the CIA as well to look into him, CNN has learned.

But what was provided by the Russians in late September 2011 was "basically the same" information that had been given the previous March to the FBI, according to a government official.

The source said the communication was a "warning letter" sent to the CIA.

Tsarnaev, 26, suspected along with his younger brother of bombing the Boston Marathon early last week, died on Friday following a violent confrontation with police.
