An Islamic State suicide attack on a coalition base in northern Iraq was foiled Saturday without Iraqi or coalition casualties, officials said.

U.S. Army Col. Ryan Dillon, the coalition spokesman, said on Twitter that one attacker prematurely detonated a suicide vest and two others were shot dead.

The U.S.-led coalition said in a statement that the trio, armed with suicide vests and small arms, tried to attack a base near the northern town of Hawija late on Saturday.
