At least 60 people were injured as hundreds of fuel vehicles exploded in a massive blaze that tore through a customs post in Afghanistan close to the Iranian border, disrupting power supplies and causing millions of dollars of damage.<br /><br />Iranian authorities sent fire engines and ambulances across the border, while scores of locals fought the blaze in the border town of Islam Qala before it was brought under control.<br /><br />Initial reports said the blaze had started after a gas tanker exploded. Officials said later that the cause was not immediately clear.<br /><br />Waheed Qatali, governor of the western province of Herat, said Iranian authorities and NATO-led personnel in Afghanistan were asked for assistance to help contain the fire, which damaged electricity infrastructure, leaving much of Herat's capital city without power.<br /><br />Thick plumes of black smoke and flames rose high into the air around the scene, television pictures showed.
