A suicide bomber has killed at least nine children and a policeman in eastern Afghanistan, police say.
The attacker, who was on a motorcycle, struck at a market in Samkani district near the Pakistan border. At least 15 other people were injured.
Local officials said a passing Nato military patrol was the target of the attack in Paktia province and coalition soldiers were among the casualties.
There was no immediate word from the Nato-led force.
