WBRZ - Baton Rouge

At least 36 people are dead and dozens injured after two female bombers blew themselves up on Moscow's subway system during this morning's rush-hour.

The first explosion happened at a train station in central Moscow underneath the building that houses the main offices of the Federal Security Service - the KGB's main successor agency.

The second blast struck another station about 45 minutes later when the bomber, wearing a belt packed with plastic explosive, set it off as the train's doors opened.

Today's attack is likely to focus on Chechen rebels and other separatist groups.
