Two explosions hit the Moscow subway system on Monday morning, killing at least 37 people, Russian news agencies reported.

The Emergency Situations Ministry said the blast which struck the Lubyanka station at 7:56 a.m. (0356 GMT) had killed 25 people and injured at least 10 others, the Itar-Tass news agency reported.

A spokesperson of the ministry told Itar-Tass that 14 people died in the wagon of the train and 11 on the platform.

Shortly afterwards, an explosion hit another subway station. Itar-Tass said at least 12 people were killed and 12 others injured in the second blast that hit the Cultural Park subway station at 8:40 a.m. (0440 GMT)

Prosecutors have opened a criminal probe into possible acts of "terrorism" after the deadly blasts.

On Feb. 6, 2004, at least 41 were killed and more than 130 others injured when a blast ripped through a crowded metro car in the Russian capital during the morning rush hour.
