Iranian authorities are investigating reports of a large explosion just east of the capital, Tehran, early on Friday, state TV reported.
Videos and pictures posted on social media that were picked up by local news outlets showed a bright light flaring out across the night sky, followed by a large plume of smoke.
Semi-official news agency Isna reported the explosion was of an industrial gas tank on the outskirts of a military defence site but had no connection to military installations in the region.
The defence ministry was quoted by Manoto news as saying a gas tank exploded in a public area in Parchin but had nothing to do with military bases there.
Parchin is home to a sprawling military base where Iranian technicians were alleged to have tested high explosive components for a nuclear warhead in the early 200s.
