Russia's Dmitry Medvedev visits site of metro bombing

Russian president Dmitry Medvedev laid flowers on Monday on the platform a central Moscow metro station where a suicide bomber killed dozens of people during the morning rush hour.

Two female suicide bombers killed at least 38 people on packed metro trains on Monday, stirring fears of a broader campaign in Russia's heartland by Islamists from the North Caucasus.

Medvedev, who after the attacks vowed to fight terrorists "to the end", entered the Lubyanka metro station outside the headquarters of the Federal Security Service (FSB), Russia's main domestic security service.

Joined by his wife and Moscow Mayor Yury Luzhkov, Medvedev placed a bouquet of red roses with a black ribbon on the platform where the blast took place, television pictures showed.
