Eight NATO service members and a contractor are dead after an Afghan military pilot opened fire on the foreign troops following a dispute at the airport in Kabul.
Wednesday’s shooting was the deadliest incident in which a member of the Afghan security forces turned against coalition forces.
NATO did not disclose the nationalities of the troops killed.
The worst incident before that occurred on April 16 when an Afghan soldier walked into a meeting of NATO trainers and Afghan troops at Forward Operating Base Gamberi in Laghman province and detonated a vest of explosives hidden underneath his uniform.
Six NATO troops, four Afghan soldiers and an interpreter were killed in that incident.
The Taliban claimed responsibility for the attack, but Defense Ministry spokesman Gen. Mohammad Zahir Azimi said the gunman was an Afghan military pilot who “opened fire on foreigners after an argument.”
The pilot was killed in the morning shooting, which occurred at a facility used by the Afghan Air Force, Azimi said.
Azimi said the shooter was a military pilot of 20 years. “An argument happened between him and the foreigners and we have to investigate that.”
An Afghan pilot who spoke on condition of anonymity, said the gunman was Ahmad Gul, a 50-year-old pilot from Tarakhail district of Kabul province.
In a statement, Taliban spokesman Zabiullah Mujahid said, however, that the gunman was impersonating an army officer and that others at the facility helped him gain access. The gunman killed nine foreigners and five Afghan soldiers, he said. The Taliban often exaggerate the number of casualties caused by their attacks.
Taliban insurgents have stepped up their attacks on government and military installations across Afghanistan.
