KABUL, Afghanistan (AP) - 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.
