At least 18 people are dead after a suicide car bomb attack on a NATO convoy in the Afghan capital.
Among those killed are 12 local civilians, five American soldiers and a Canadian soldier.
The Taliban has claimed responsibility for the strike.
NATO spokesman Josef Blotz said: “I think this is a very very tragic incident which is very deplorable because for four, five months we have not had such a tragic incident.”
The suicide attack came after the Taliban warned it plans to carry out a new offensive against the Afghan government, foreign forces and diplomats.
This in response to NATO plans to target the southern stronghold of the militants in Kandahar.
