BAGHDAD (AP) At least 10 rockets targeted a military base in western Iraq that hosts U.S.-led coalition troops on Wednesday, the coalition and the Iraqi military said. It was not immediately known if there were any casualties.

The rockets struck Ain al-Asad airbase in Anbar province at 7:20 a.m., spokesman Col. Wayne Marotto said.

Later, the Iraqi military released a statement saying the attack did not cause significant losses and that security forces had found the launch pad used for the missiles. An Iraqi military official said they had been found in the al-Baghdadi area of Anbar, speaking on condition of anonymity because they were not permitted to brief media.

It was the first attack since the U.S. struck Iran-aligned militia targets along the Iraq-Syria border last week that killed one militiaman, stoking fears of a possible repeat of a series of tit-for-tat attacks that escalated last year, culminating in the U.S.-directed drone strike that killed Iranian Gen. Qassim Soleimani outside the Baghdad airport.

Wednesdays attack targeted the same base where Iran struck with a barrage of missiles in January last year in retaliation for the killing of Soleimani. Dozens of U.S. service members were injured, suffering concussions in that strike.
