Four metro stations in St Petersburg have reopened after being closed following a bomb threat.

Russian news agencies say the St Petersburg subway stations shut down after a bomb threat have reopened.

At least four stations were closed on Tuesday after a call about a possible bomb.

The bomb scare follows a train bombing on Monday that killed at least 14 people in Russia's second-largest city.
