Another bomb has gone off in southern Russia today. Overnight, at least two people were killed when their car blew up in the North Caucasus republic of Dagestan, which borders Chechnya. The attack came after a dozen people, most of them police officers, were killed in two suicide bombings on Wednesday.
Separately, a Muslim Chechen militant leader has claimed responsibility for Monday's twin suicide bombings on Moscow's subway system. According to the New York Times, Doku K. Umarov posted a statement to the Internet, saying the attacks were an act of revenge for the killing of civilians by Russian security forces and that there are more to come.
“You Russians hear about the war on television and the radio, and this is why you are quiet, this is why you don’t react to the atrocities committed by the bandit group that is led by Putin,” Mr. Umarov said on the video.
Thirty nine people were killed and dozens wounded in the Moscow bombings on Monday.
Meanwhile, Russian Prime Minister Vladimir Putin is vowing to "drag out of the sewer" the terrorists who plotted this week's deadly subway bombings in Moscow.
