Baghdad – Iran launched a missile attack on U.S.-led forces in Iraq in the early hours of Wednesday in retaliation for the U.S. drone strike on an Iranian commander whose killing has raised fears of a wider war in the Middle East.

Iran fired more than a dozen ballistic missiles from its territory against at least two Iraqi facilities hosting U.S.-led coalition personnel at about 1:30 a.m. (2230 GMT), the U.S. military said.

U.S. President Donald Trump said in a tweet late on Tuesday that an assessment of casualties and damage from the strikes was under way and that he would make a statement on Wednesday morning.

“All is well!” Trump, who visited the al-Asad air base in December 2018, said in the Twitter post.

One source said early indications were of no U.S. casualties. Other U.S. officials declined to comment.
