Nato troops killed in Afghanistan
Two coalition service members have been killed by a bomb in volatile southern Afghanistan, Nato said.
No further details or the nationalities of those who died have been released.
An Afghan official in Kandahar said a suicide attack on Nato troops had also killed civilians, but it was not immediately clear if the two incidents were the same.
The attacker was on a motorbike, said provincial spokesman Zelmai Ayubi.
He did not have casualty figures for either troops or civilians.
Nato and Afghan troops began a major operation to wrest back control of the south from the Taliban insurgency in July.
They have established some pockets of security but insurgents still carry out daily attacks and bombings.
In a separate incident, a remotely piloted aircraft has crashed in Behsud district in eastern Nangarhar Province.
Nato said it was not carrying any weapons and the crash was not believed to be the result of enemy activity.
Remote-controlled drones are widely used in both Afghanistan and over the border with Pakistan for surveillance and to target insurgent leaders.
