The US military had advance warning of an incoming rocket barrage from Iran at two bases in Iraq, giving troops time to reach shelter, according to a report Wednesday.

Tehran fired more than a dozen missiles at the bases that house US and coalition forces in retaliation for a drone strike that killed Iran’s top military leader, Qassem Soleimani, last week.

“The early warning system worked,” a US official told USA Today.

A total of 15 surface-to-surface missiles were fired by Iran, US officials.

Ten hit the Ain al-Assad air base and one struck a base in Erbil, while the other four failed.

The Pentagon said no casualties were reported and it was still assessing damage to the bases, but it appeared that a hangar at Assad was damaged.

Following the attacks Tuesday evening, President Trump tweeted that “All is well!” and said he would be “making a statement” Wednesday morning.

There are about 5,000 US troops stationed in Iraq.
