The metro line in Moscow, shut off following two suicide bomb attacks, has resumed operation late on Monday.

Passengers and reporters were allowed into the Lubyanka station by 05:10 p.m. local time (1310 GMT), with the Cultural Park station being reopened earlier, and traffic had returned to normal along the line, the subway's spokeswoman said.

At the platforms of the two stations, some citizens were seen dedicating flowers to the victims.

Two deadly blasts struck the Lubyanka and Cultural Park subway stations in central Moscow during rush hours on Monday morning, with an interval of around 45 minutes, killing at least 37 people and injuring about 65 others.

The blasts were confirmed as having been set off by two female suicide bombers who probably were linked to terrorist groups in North Caucasus.
