During the Gulf War, Fallujah suffered one of the highest tolls of civilian casualties. Two separate failed bombing attempts on Fallujah's bridge across the Euphrates River hit crowded markets, killing an estimated two hundred civilians. The first bombing occurred on 14 February 1991, when a British jet intending to bomb the bridge dropped two laser-guided bombs on the city's main market. Between 50 and 150 civilians died and many more were injured. In the second incident, Coalition forces attacked Fallujah's bridge over the Euphrates with four laser-guided bombs. At least one struck the bridge while one or two bombs fell short in the river. The fourth bomb hit another market elsewhere in the city, reportedly due to failure of its laser guidance system.
