At least 16 people are killed and 40 injured by two female suicide bombers in an attack at Krylya, a popular music festival, at the Tushino airfield near Moscow. The Russian authorities blame an on-going terrorism campaign by Chechen rebels; the Chechen government denies any connection to the attacks.
2003 occupation of Iraq: 7 newly US-trained Iraqipolicemen are killed and at least 13 are wounded by an explosion while they are marching from training school in Ramadi. The American forces overseeing the rebuilding of Iraq's infrastructure, who gave their blessing to the march taking place, blames loyalists to Saddam Hussein; some people on the scene blame U.S. forces. It is the first attack on Iraqis collaborating with the invading coalition forces, as opposed to on the forces themselves.
