Russian authorities this week turned over information about Boston Marathon bomber Tamarlan Tsarnaev and his mother Zubeidat Tsarnaeva, including the fact that mother and son discussed jihad in a telephone conversation in 2011, and that Zubeidat also spoke about jihad with a man in Russia who is under investigation by the FBI. Mother and son were added to the CIA’s terrorism database in late 2011. Regarding the alleged use of chemical weapons in Syria, the US has said it seeks “strong evidence” before deciding on a response.
