A massive explosion at a military arms depot near the Iranian capital killed 15 servicemen on Saturday and seriously wounded several others,in what officials were treating as an accident.
A spokesman for the Revolutionary Guards said the blast happened as troops were moving munitions at a base in Bidganeh,near Shahriar.
My dear colleagues in the Revolutionary Guards were moving munitions in one of the arsenals at that base when,due to an incident,an explosion happened, Ramezan Sharif told state TV news channel IRINN.
Some of the casualties are reported to be in a critical condition, he added.
Residents in western suburbs of Tehran,45 km away,said they felt the blast,assuming it to be an earthquake. Some reports said the initial blast was followed by a second explosion.
There were no reports linking the blast to any air strike or other attack.
