A rogue Afghan army officer shot dead six Nato soldiers before being killed himself today.
The man, a pilot, opened fire “after an argument” an Afghan Defence Ministry spokesman said.
It was the latest in a spate of deadly incidents that have occurred inside government or military installations, a favourite target of Taliban insurgents.
The Taliban claimed responsibility for the attack, but the Defence Ministry insisted it was not a terrorist attack.
Nato did not disclose the nationalities of the casualties pending notification of their families. The airport is home to the Nato Air Training Command.
A Nato spokesman said small arms fire was reported at the airport at about 10.25am local time.
“A quick-reaction force responded to the incident,” he said. “At this time there are reports of Nato casualties.”
The defence spokesman 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 asked not to be named, said the gunman was Ahmad Gul, a 50-year-old from Tarakhail district of Kabul province.
The Taliban claimed the gunman was impersonating an army officer and that others at the facility helped him gain access.
Since March 2009, the coalition has recorded 20 incidents where a member of the Afghan security forces or someone wearing a uniform used by them attacked coalition forces, killing a total of 36.
Half of the 20 incidents involved the impersonation of an Afghan policeman or soldier. The cause of the other 10 incidents were attributed to combat stress or unknown reasons. The officers insisted that so far, there is no solid information that an insurgent was directed to join the army for the purpose of conducting attacks.
