Four members of Iraq’s military were wounded on Sunday in a rocket attack targeting an air base just north of Baghdad where American trainers are present, Iraqi security officials said, according to The Associated Press.

At least six rockets were fired toward the base, in an attack which comes days after Iran fired ballistic missiles at two bases in Iraq that house US forces, causing no casualties.

Sunday’s attack wounded an Iraqi air force officer and three enlisted men, Iraqi security officials said. They spoke on condition of anonymity in line with regulations.

No group claimed responsibility for the attack, noted AP.

The rockets struck Balad air base, which hosts American trainers, advisers and a company that provides maintenance services for F-16 aircraft. Some rockets fell on a restaurant inside the airbase, the officials said.

The base is located some 50 miles (80 kilometers) miles north of Baghdad.

A statement from the Iraqi army’s official media office confirmed the attack but said eight rockets hit the base, and that two officers had been wounded. The difference in accounts could not immediately be reconciled. Read more at Arutz-7
