A suicide bomber has blown himself up in the Afghan city of Jalalabad, killing at least 10 people, government officials said, but no militant group has yet claimed reponsibility for the attack.
Inamullah Miakhel, a spokesman for the provincial health department, confirmed the deaths and said four wounded people were taken to hospital.
The attacker detonated his explosives near a petrol station, causing a large fire, officials said.
"Most of the victims were children, who were working in a car wash close to the suicide bombing site," said Sohrab Qaderi, a local official.
Eight cars were burnt in the explosion.
