BBC News - Afghanistan: Deaths in Kabul airport military spat Several people have been killed or wounded after an Afghan air force officer exchanged fire with foreign troops at Kabul airport during an argument, the defence ministry says. The incident apparently took place at a facility used by the Afghan air force at around 1100 local time (0630 GMT), ministry spokesman Gen Mohammad Zahir Azimi said. The ministry gave no further details. A Nato spokesman confirmed the shooting and the casualties. "We can confirm there was small arms fire during this incident, we're also aware that there are some Isaf casualties," said International Security Assistance Force spokesman Maj Tim James. "We believe the incident has now concluded and we don't know how the shooting started." Witnesses reported hearing sirens and seeing a heavy military presence near the facility. The Taliban claimed responsibility for the incident in a text to the Associated Press news agency, but the authorities have not confirmed any insurgent activity. Correspondents say rapid recruitment into the Afghan military has raised fears of Taliban infiltration into the police and army. Nato's exit strategy for Afghanistan involves progressively handing over to the local security forces. But there have been a number of attacks recently on foreign forces by Afghan security personnel. The deadliest was last November when an Afghan policeman killed six US soldiers. And two Nato soldiers were shot dead by an Afghan border policeman in northern Faryab province on 4 April, local officials said.
