HEART, Aug 25: At least 11 people including several children were killed in a series of explosions at an Afghan gas storage facility, which triggered a massive inferno in a nearby camp for displaced people, officials said Tuesday. It was not immediately clear whether the blasts late Monday on the edge of the relatively peaceful western city of Herat were the result of an accident or caused by a militant attack. “Around midnight (Monday) a gas tanker exploded which triggered blasts in a gas storage plant, killing 11 people and injuring 10 others,” Herat police spokesman Abdul Rauf Ahmadi told AFP. The explosions triggered a plume of flames into the night sky, which rapidly spread to a nearby camp for internally displaced people where most of the deaths occurred. Ihasanullah Hayat, spokesman for the governor of Herat, confirmed the toll and said several children were among those dead. Domestic gas cylinder explosions are an almost daily occurrence around the country, where safety standards are poor and fatal accidents not uncommon.
