A suicide bomber blew himself up on Tuesday in the Afghan city of Jalalabad near a security forces vehicle. The attack left at least 10 people dead, government officials said. No militant group has yet claimed responsibility for the attack. Inamullah Miakhel, a spokesman for the provincial health department in the eastern city, confirmed the death of 10 people and said others were taken to a hospital. The attacker detonated his explosives near a petrol station, causing a large fire, officials said, according to Reuters. "Most of the victims were children, who were working in a car wash close to the suicide bombing site," said Sohrab Qaderi, a member of the provincial council. Some of the victims were brought to hospital with severe burns, health director Najibullah Kamawal said. "I saw a big ball of fire that threw people away. The people were burning," Esmatullah, who witnessed the incident, told AFP. Jalalabad, the capital of Nangarhar province, has been the scene of numerous attacks recently as militants step up activity in the restive region.
