The French government says an Afghan soldier has shot and killed two members of the French Foreign Legion in eastern Afghanistan.

President Nicolas Sarkozy's office said a soldier in the Afghan National Army opened fire on the troops Thursday in the Tagab Valley of Kapisa province.

NATO issued a statement earlier saying a man wearing an Afghan National Army uniform killed two coalition service members in the country's east, but did not give details.

Meanwhile in southern Afghanistan, a roadside bomb killed 10 Afghan police officers on Thursday.

Provincial officials say the police had just left a training center and were headed home when their vehicle hit a landmine in the Nad Ali district of Helmand province.

New police recruits were among those killed. One police officer was wounded in the attack.

The Taliban claimed responsibility for the bombing.
