At least 10 rockets struck an Iraqi military base in western Iraq on Wednesday that houses troops from the US-led coalition, a coalition spokesman said.
The rockets hit the Ain al-Asad air base in Anbar province at 7:20 am, spokesman Col. Wayne Marotto said. It was not immediately known if there were any casualties.
It was the first attack since the United States struck targets of Iranian-aligned militias along the Iraq-Syria border last week.
The US attack was in response to a series of rocket attacks directed at the US presence, including one that killed a Philippine coalition contractor outside the airport in Irbil City in northern Iraq.
After that attack, the Pentagon said it was a “proportionate military response” taken after consulting coalition partners.
Marotto said Iraqi security forces were leading an investigation into Wednesday’s attack.
