8 Rockets Hit Iraqi Air Base

Eight rockets landed on an Iraqi air base Sunday and injured four Iraqi officers—but who perpetrated the attack remains unclear. Iraq's military says the Katyusha rockets struck Balad Air Base, which hosts foreign contractors and US troops roughly 46 miles north of Baghdad, CNN reports. Al Jazeera notes that the base also hosts US trainers, advisers, and a company that maintains F-16 aircraft. Most of the US airmen stationed there had left before the missiles arrived. No one has claimed responsibility for the strike, which comes days after Iran fired ballistic missiles at Iraqi bases amid fever-high tensions between Washington and Tehran. (More Iraq stories.)
