February 12-13, 1991: US Kills 400 Iraqi Civilians in Air Strike
A US air and missile strike in Baghdad destroys three major bridges, but also kills around 400 civilians in a blockhouse being used as an air-raid shelter. Iraqi officials later confirm that the blockhouse also housed a military communications center, and may have been a military command center as well. [PBS Frontline, 1/9/1996; NationMaster, 12/23/2007]
