TEHRAN, Feb. 14 (MNA) – A massive blast and subsequent fire on Saturday at a customs outpost in western Afghanistan on the border with Iran left more than 60 people injured and destroyed hundreds of trucks.

A fuel tanker exploded at the Islam Qala crossing in Afghanistan's western Herat province causing a massive fire that consumed more than 500 trucks carrying natural gas and fuel, according to Afghan officials and Iranian state media.

It was not immediately clear what caused the blast. Wahid Qatali, Herat’s provincial governor, said Afghan first responders along with Iranian forces put the fire out after several hours.
