NATO says a man wearing an Afghan National Army uniform has killed two coalition service members in eastern Afghanistan.

NATO did not give further details of Thursday's incident and only said that the individual turned his weapon against two NATO soldiers, killing them.

The victims' nationalities were not identified.

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.
