At least 60 people were injured as hundreds of fuel tankers exploded last week 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.
Investigators have begun sifting through the ruins of a massive fire that destroyed hundreds of fuel tankers parked at a major crossing at the Afghanistan-Iran border, governor of Afghanistan's Herat province said.
The cause of the explosion and ensuing fire were still undetermined on Tuesday.
Satellite photos of the Islam Qala customs terminal and surroundings analysed by The Associated Press show the devastation wreaked by a blaze that began on Saturday when a fuel tanker exploded. The flames roared out of control for nearly three days.
Satellite images from Planet Labs Inc. obtained by the AP show the burnt shells of hundreds of fuel and natural gas tankers on the Afghan side of the border.
Typically, hundreds of tankers line up there while passing between the two countries.
Thousands of trucks crowded
At least 60 people were injured when the explosion set off a huge fire that engulfed many of the hundreds of trucks lined up at the border crossing.
Officials say there were some 2,500 trucks there at the time of the fire. The customs holding area was made to accommodate no more than 700 tankers at a time but routinely hundreds more crowd into the area.
A strike by truckers protesting increased government taxes was in its second week at the time of the fire and was the reason for the extraordinary number of tankers parked at the crossing, said Younus Qazizada, Herat Chamber of Commerce president.
Herat firefighters with only limited capability said the fire was out of control almost from the initial moments.
The satellite images show a mass of burned trucks, the ground around them singed black. The fire burned through an area just under a half a square kilometre (a fifth of a square mile). More trucks had lined up after the fire and other cars and people appeared to be gathered at the site on Tuesday.

Major transit point
The crossing, around 120 km west of the city of Herat, the provincial capital, is a major transit route between Afghanistan and Iran.
The United States allows Afghanistan to import fuel and oil from Iran as part of a special concession that exempts Kabul from US sanctions against Iran.
