Blast near a military base in Tehran, Iran

A large explosion in the capital of Iran, Tehran, was witnessed on Friday which seemingly has played a role in the country’s past nuclear testing activities.

Social media were filled by the pictures and videos of this incidents and were later on picked up by the local news outlets. Witnesses said the blast came from the direction of Parchin, a major military site. In the videos, bright light is flaring out across the sky followed by a large plume of smoke.

According to the defense ministry spokesperson Davoud Abdi told state TV the blast happened at a gas storage facility in a “public area” of Parchin rather than the military base. The fire had been put out and no casualties had been reported, he added, but gave no details about the cause of the blast.

“Our colleagues are present on the ground and investigating the incident carefully,” Abdi said.

This is the same area where the Iranian technicians had allegedly done tested high explosive components for a nuclear warhead in the early 200s, a claim Iran has denied.

Anything confirmed is yet to be known. This surely has sharpened the edges of rival nations and they will be sure to keep an open ear to whatever happens in Iran. As the Guardian reports, In 2014, the military site was suspected to have been damaged by a fire or explosion of the same circumstances, but investigations by the International Atomic Energy Agency were shot down due to having no access to the area.

It remains to be seen if there is more this gas explosion or not.
