SAINT PETERSBURG: Russian President Vladimir Putin went to lay flowers late Monday at the scene of the deadly blast that hit Saint Petersburg's metro, an AFP photographer said.

Putin, who made no comment, left a bouquet of red flowers at the entrance to the Technological Institute metro station where 11 people were killed and dozens injured on Monday afternoon in what authorities are investigating as a suspected terror attack.
