Iran explosion at Tehran military base
A huge explosion has rocked a military base west of Iran's capital, Tehran, officials say.
Several people were killed after the blast inside a Revolutionary Guards weapons depot, according to the semi-official Fars news agency, but this has not been confirmed.
Windows in nearby buildings have been shattered and the blast was heard in central Tehran, 40 km (25 miles) away.
A helicopter and ambulances have reportedly been sent to the scene.
Local MP Hossein Garousi said "a large part of an ammunition depot exploded," parliament's website reported.
It is not clear what caused the explosion in the village of Bidganeh, near the city of Karaj.
Karaj resident Kaveer told the BBC's Newshour programme that the sound was "deafening".
