KABUL, Afghanistan (AP) — France suspended its training operations in Afghanistan and threatened to withdraw its entire force from the country early, after an Afghan wearing an army uniform shot and killed four French troops today and wounded others.

The attack was the second time this month an Afghan soldier has killed French forces.

It was the latest in a series of attacks by members of the Afghan security forces, or those dressed in their uniforms, against coalition partners that have raised fears of increased Taliban infiltration of the Afghan police and army as foreign combat forces prepare to withdraw from the country by 2014.

The impact of the French suspending training operations is unclear, but it would result in a major setback for the U.S.-led coalition if other troop- contributing nations stopped training Afghan national security forces or decided to pull out earlier than planned.

French officials said the attack happened during a training exercise at a base jointly operated by French and Afghan forces.
