The American military has confirmed, in a released statement, that a rocket attack on an Iraqi base, where U.S. and coalition troops are based, has killed an American and a British soldier and an American contractor.

The three men were killed on Camp Taji base as 18 Katyusha rockets slammed into the base on Wednesday at 1935 hours local time. Camp Taji hosts U.S. and coalition personnel for training and advising missions.

Their names will not be released pending notification of next of kin.

At least 12 personnel were wounded during the attack, the statement added.
