ST. PETERSBURG, Apr 3 (PRIME) -- Ten people were killed by explosions that ripped through two stations of the St. Petersburg metro, Sennaya Ploshchad and Tekhnologicheskiy Institut, a source in the emergency services told PRIME on Monday.

“Preliminarily, there were two explosions on stations Sennaya Ploshchad and Tekhnologicheskiy Institut,” the source said.

The source added that information about victims is unclear so far. “Preliminary information: 10 people are dead, the figure is to be clarified.”

All the metro stations were closed for entry and exit at 3:40 p.m., local time, a spokesperson for the metro said.

The prosecutors have already started investigation, a spokesperson for the Prosecutor General’s Office said.

President Vladimir Putin, who is in St. Petersburg, said that the investigators are considering an accident and a criminal action as possible reasons behind the explosions. “The reasons are unclear so far, this is why it is too early to say. Investigation will show.
