KABUL: Gasoline tanker trucks burst into flames in Kabul overnight, killing at least seven people and starting large fires that caused power cuts to some parts of the Afghan capital, officials said on Sunday.

The tankers were parked in northern Kabul and burst into flames late on Saturday, according to the Ministry of Interior. Fourteen people were injured.

Tariq Arian, the ministry of interior spokesman, said authorities were still investigating how the fire started and did not yet know the cause, but he ruled out a "terrorist incident." Two security sources had earlier told Reuters they believed it was caused by a Taliban rocket fired in the area. But Taliban spokesman Zabihullah Mujahid has said they were not involved.
