"One person was killed and 10 firefighters injured in a fire and explosion in a cabin at a military facility in the capital," Tehran Fire Department spokesman Jalal Maleki told the Mehr news agency.

"Following the fire in the cabin, it exploded due to the accumulation of heat and vapours inside while the doors and windows were shut," he added.

The Islamic Revolutionary Guards Corps, the ideological arm of Iran's military, said it operated the base where the fire broke out.

"Following a fire incident in the afternoon at one of the IRGC's Navy centres, one of the on-duty personnel of the force, Mostafa Abdollahi, was martyred," it said in a statement, adding that several firefighters were injured.
