Twelve Turkish military officers were killed when a helicopter of foreign soldiers crashed in Bagrami district in the east of capital Kabul, an official said on Friday.
The incident took place in Hussainkhel area of the district at 10:30am where 12 corpses of Turkish soldiers had so far been recovered, the 101 Asmayee Police Zone chief, Brig. Gen. Mohammad Zahir told Afghan media.
The helicopter crashed due to technical problems and fell on an ordinary house where there are fears that the incident might have also caused fatalities to the residents, he said.
Police have cordoned off the scene and an investigation was underway, he added.
There was no immediate comment on the crash from NATO or from Turkey, which has more than 1,800 soldiers serving in Afghanistan, most of them around the capital.
Unlike other European members of the NATO-led coalition, Turkey's mission is limited to patrols and its soldiers do not take part in combat operations.
In January, six US Marines were killed in a helicopter crash in southern Afghanistan, which followed the death of 30 American personnel, including 22 Navy SEAL commandos, in eastern Afghanistan in August last year.
