A suicide bomber wounded six people in the capital of Chechnya on Wednesday, officials said - the latest in a series of attacks undermining Kremlin claims that stability is returning to the southern Russian region.
Chechen Interior Minister Ruslan Alkhanov said the bomber was a woman - a fact that harkened back to the early 1990s, when female suicide bombers called "black widows" became a hallmark of the Chechen insurgency. Two Russian passenger airliners were destroyed by "black widows" and others committed fatal bombings near Red Square and at a Moscow subway station.
Wednesday's attacker detonated her belt when two police officers walked by, seriously injuring them and wounding four civilians in a nearby car, officials said.
Earlier reports said the two policemen had been killed.
