An Iraqi military base, where U.S.-led coalition troops are based, was hit with 10 rockets Wednesday. This is the latest in a series of rocket attacks in Iraq just days before Pope Francis is due to visit the country.

The rockets targeted Ain Al-Asad airbase, northwest of Baghdad, at 7:20 a.m. local time Wednesday (11:20 p.m. Tuesday ET). Colonel Wayne Marotto, the military spokesman for Operation Inherent Resolve, took to Twitter to confirm the attack.

Iraqi security forces are leading the response and investigation, Marotto added. No one has claimed responsibility for the attack yet. 

There were no immediate reports of any casualties. But CBS News reported that a contractor died of a heart attack after the missile attack. His nationality is unknown.
