President Trump backed away from further military action against Iran and called for renewed diplomacy on Wednesday as the bristling confrontation of the past six days eased in the aftermath of an Iranian missile strike that seemed intended to save face rather than inflict casualties.

President Donald Trump said Wednesday that Iran appears to be “standing down” and no Americans or Iraqis were harmed in Iran’s missile strike on two Iraqi bases housing U.S. troops.

Iran attacked two bases in Iraq that house American troops with a barrage of missiles early Wednesday, Iranian official news media and United States officials said, fulfilling Tehran’s promise to retaliate for the killing of a top Iranian commander.

Iran has begun an attack on the United States with missiles fired at an American base in western Iraq, Iranian official news media said early Wednesday.

For many of the soldiers, it would be their first mission. They packed up ammunition and rifles, placed last-minute calls to loved ones, then turned in their cell phones. Some gave blood.
