Russia bus bomb: Volgograd blast kills five

An explosion that killed at least five people on a bus in the southern Russian city of Volgograd was caused by a bomb, Russia's National Anti-Terrorism Committee has said in a statement.

The blast, which happened just after 14:00 (10:00 GMT), also injured more than a dozen people, many seriously.

No-one has yet said they carried out the attack.

Cities to the south, in Russia's North Caucasus, have seen attacks by Islamist militants in recent years.

It is believed there were 40 people on board the bus, the BBC's Steve Rosenberg in Moscow reports.

Explosives experts are currently on the scene sifting through the wreckage, our correspondent adds.
