NEWS; NATO disputed the Taliban claim

"We do not know why it started but there is no indication that a suicide bomber was involved and there are no reports that someone managed to get into the base to do this," the NATO-led force said in a statement.

The Taliban has claimed responsibility for previous conflicts between NATO service members and members of the Afghan military. CNN could not independently verify the group's claims.

The Taliban said the man was once a pilot in an Afghan regime in the late 1980s and early 1990s.

"Since the current Afghan air forces have no planes so, he was just going to Kabul airport to show up and earn his salary for a long time," Mujahid told CNN.

The man "was holding the rank of colonel at the time and he had an AK-47 with him. After his bullets were finished, then he was shot to death by armed forces," Mujahid told CNN.

There was confusion about the death toll. The NATO-led force initially said six service members were killed. It raised that toll to nine but backed away temporarily before saying again that the shooting killed nine people -- eight international service members and a civilian contractor. The Pentagon confirmed that all were Americans.

Violence between Afghan forces and NATO troops is a matter of extreme concern for NATO officials, and it is growing in frequency.

There have been 36 NATO deaths in the past two years attributed to attacks by people perceived to be Afghan soldiers or police. Officials fear that the increasing frequency of the attacks could undermine trust between NATO troops and the Afghans they are working hard to prepare so they can eventually take over security in the country.

The Taliban's claim that the Afghan gunman was their recruit follows a now familiar pattern of the insurgency stating that attacks are theirs, even though NATO later suggests the gunman was acting out of personal motivation.

Out of 16 incidents of Afghan forces shooting NATO personnel that NATO has investigated, eight have been determined to be motivated by combat stress on the part of the Afghan attacker. The other eight investigations are undetermined.
