One American was killed and another injured in a shooting in Kuwait on 21 January. Both were civilian contractors for the US military, and the shooting took place near the Camp Doha military base north of Kuwait City and near the Iraqi border. No one has yet claimed responsibility. It is the third such incident in the past few months: in October, two US marines were shot, one fatally, by two Afghanistan veterans, prompting a government crackdown on suspected Al-Qaeda-linked militants in the country. In November, two American soldiers were injured when shot by a Kuwaiti policeman on a highway south of the capital. US forces have had a presence in Kuwait since the end of the 1990-91 Gulf war, but have more than doubled in strength over the past year in preparation for a possible attack on Iraq.
