Two gunmen attacked a police traffic station on a highway 12 miles from Moscow today, armed with guns and axes, and four terrorists killed in St. Petersburg after bombs exploded in apartment building.

UPDATE: Video of weapons seized in St. Petersburg anti-terrorism operation

Two officers were injured in the attack on the police station outside Moscow.

Also, two explosions rocked an apartment building and four militants were killed in an anti-terror operation in St. Petersburg.

There are still many questions left unanswered at this early stage about St. Petersburg. Were these coordinated attacks? Did the bombs go off as a result of an anti-terror operation or were they the cause of the operation?

Updates will be posted as information becomes available.
