According to the report, the strong blast took place in one of Tehran's suburbs as a military convoy left a Revolutionary Guards' ammunition storehouse. At least 15 people were killed in the explosion.
Western sources reported that the blast took place on July 19 and that the convoy was carrying military equipment for the Lebanese terror organization.
It was also reported that senior Revolutionary Guards officials banned the Iranian media from reporting the explosion, even though it was heard throughout the capital. The Guards launched an investigation into the incident.
An official source told the newspaper that the strong explosion was heard across Tehran, adding that the Revolutionary Guards were trying to silence the incident despite the fact that many people were killed.
Additional explosions and mysterious incidents which have taken place in Iran recently are being investigated by the Revolutionary Guards. In one of the incidents, a blast rocked a mosque in the city of Shiraz, where weapons were being displayed, killing 11 people.
Iranian Intelligence Minister Gholam-Hossein Mohseni Ejei said following the incident that the main suspect in the affair was arrested.
"The terrorist group had ties with the US and Britain. These countries were informed of the arrest by the Foreign Ministry," he said, "but the countries did nothing to prevent these terror groups' activity."
