BAGHDAD (AP) — At least 10 rockets targeted an Iraqi military base in western Iraq on Wednesday that hosts U.S.-led coalition troops, a coalition spokesman said.

The rockets struck Ain al-Asad airbase in Anbar province at 7:20 a.m., spokesman Col. Wayne Marotto said. It was not immediately known if there were any casualties.

It was the first attack since the U.S. struck Iran-aligned militia targets along the Iraq-Syria border last week.
