According to them, firefighting teams have been sent to the scene.
Eyewitnesses meanwhile said at least 10 gas tankers have caught fire.
No further details have been released but unconfirmed reports indicate an initial explosion was heard before the fire broke out.
This comes after February’s massive fire at the customs complex at the Islam-Wala customs post on the border between Herat province and Iran.
A fuel tanker exploded, which set off an enormous fire that spread to more then 100 tankers – resulting in over $50 million in losses to business owners.
