The Associated Press is reporting that a huge explosion occurred on Friday that rattled Tehran and lit up the horizon. The site of the blast was a region where many nuclear experts believe Iran conducted high-explosive tests relating to its nuclear program.

The explosion happened in the Alborz mountains, just east of the city. Satellite photos show the massive extent of the blast.
