Exactly a week after two Russian planes crashed in what official say were terrorists attacks, at least 10 people were killed and 51 wounded in a suicide attack on Tuesday night near the entrance of a crowded metro station in Moscow.
According to Moscow Mayor Yuri Luzhkov, who rushed to the blast site with top police and security officials, the suicide bomber -- a woman -- blew herself in the thick crowd near the entrance of Rizhskaya subway station.
"The woman, who had explosives almost one kilo equivalent of TNT filled with nuts and bolts, was heading for the metro station. However, on seeing two policemen checking documents, she turned back and blew herself in the thick crowd," Luzhkov said.
The whole area was cordoned off and at least two dozen ambulance vans were ferrying injured to nearby hospitals.
"There was a powerful blast and then a smaller one. I thought my roof would come off," a witness who was driving past the blast site said.
Another witness said, "There were people lying in the square. There were pieces of bodies... We were walking through pieces of people."
