UK Foreign Minister Dominic Raab said Monday’s attacks on US-led forces in northern Iraq were "outrageous and unacceptable". Rockets made in Iran were fired at Erbil International Airport in the semi-autonomous Kurdistan region of Iraq at about 9.30pm local time. The attacks killed a civilian contractor and injured a US service member, as well as nine others. "Last night’s attacks on @coalition forces and civilians in Erbil were outrageous & unacceptable," Mr Raab wrote on Twitter. "Iraqis won’t forgive militias putting Iraq’s stability at risk." At least three rockets were fired at the airport, one of which hit a military complex where US-led coalition troops are stationed. There were several blasts and a fire blazed for a few minutes near the airport, Reuters reported. Two other missiles hit residential areas near the airport, a source said. The airport reopened on Tuesday afternoon and flights resumed, authorities said. It was unclear whether the attack was aimed at international forces or the airport. The Kurdish region's interior ministry said counterterrorism, security and police units immediately launched an investigation, in co-ordination with coalition forces. Officials found a vehicle they suspected the rockets were fired from. "The vehicle was a Kia and it was located between Erbil and Gwer," the ministry said. "Last night’s attack employed the same method and technique used in a previous assault on Erbil airport.” Monday’s attack was the first time a US military or diplomatic installation has been attacked in Iraq in almost two months.
