BAGHDAD — The U.S.-led coalition in Iraq says at least 10 rockets have targeted a military base in western Iraq that hosts American troops, resulting in at least one death.

The rockets struck Ain al-Asad airbase in Anbar province at 7:20 a.m. on Wednesday, according to coalition spokesman Col. Wayne Marotto.

Pentagon spokesperson John Kirby said Wednesday that a U.S. contractor “suffered a cardiac episode while sheltering” and died shortly afterward.

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

It also comes two days before Pope Francis is scheduled to visit Iraq in a much-anticipated trip that will include stops in Baghdad, southern Iraq and the northern city of Irbil.
