Iran's Revolutionary Guard says it has begun a two-day land military exercise to upgrade its capabilities to defend the country against possible external threats.
Commander of Revolutionary Guard's ground forces Mohammad Pakpour said on the force's website sepahnews.com that the maneuvers dubbed Valfajr, or Dawn, began Sunday outside the city of Yazd in central Iran.
The Guard is Iran's most powerful military unit.
The exercises are the latest in a series of manoeuvers held amid escalating tensions between Iran and the West over Iran's nuclear program. The US and Israel have not ruled out military strikes against Iran's programme, which they say aims at developing weapons technology. Iran says the programme is for peaceful purposes.
