A major blaze broke out as several oil tankers caught fire after one of the tankers exploded at the Islam Qala port in Afghanistan's Heart Province Saturday afternoon, local media reported.

Local authorities said they lack the required facilities to quench the inferno and have offered no comments on possible casualties.

The port connects the insurgency-battered Afghanistan to Iran. Province's governor Waheed Qatali said authorities have sought Iran's help to extinguish the flames.
