Aides to Russian President Vladimir Putin say he and President Barack Obama have agreed to intensify contacts between their security agencies on fighting terrorism, especially in light of the Boston Marathon bombings.
Putin and Obama spoke by telephone on Monday at the U.S. president's initiative, the aides were quoted as saying by Russian news agencies.
Kremlin foreign affairs adviser Yuri Ushakov said the conversation focused on "the problem of intensifying cooperation of the special services in the context of the recent terror act in Boston." The suspected bombers hail from a Russian region troubled by militancy.
Ushakov was quoted as saying "practical agreement was reached on very active contacts."
Ushakov also said the presidents stressed the importance of security at the 2014 Winter Olympics in the Russian city of Sochi.
