The second explosion occurred 45 minutes later at Park Kultury station in central Moscow, killing at least 12 people and injuring seven others.

Russian security officers said terrorists could be to blame for the bombing attacks while Interfax news agency was quoted as saying that the explosive device is tied to suicide bombers. Russian Prosecutors are opening an investigation.

Emergency crews are at both blast sites. The total number of casualties is expected to get high because the two blasts occured at rush hour./.
