WASHINGTON (Reuters) - The FBI in 2011 interviewed the elder of the two brothers who are suspects in Monday's deadly Boston Marathon bombings, acting at the request of an unidentified foreign government, a U.S. law enforcement source said on Friday.
The FBI's dealings with Tamerlan Tsarnaev - who died overnight in a shootout with police - did not produce any "derogatory" information, and the matter was put "to bed," said the source, speaking on condition of anonymity.
