Iran claims success in war games

"The medium-range Kowsar missile is capable of combatting electronic jamming systems and it cannot be thrown off course by any instruments," state television reported.

It touted the Kowsar, which means "a spring in heaven" in Farsi, as a "super-modern" weapon.

Iran also said it successfully tested a "domestically developed" hydroplane with the television showing a small one-pilot craft flying some 10 metres (30 feet) above the surface of the water.

The one-propeller craft "is invisible to radar" and "can carry weapons and aim at various targets while on the move", said Rear Admiral Mohammed Ebrahim Dehqani, spokesman for the manoeuvres codenamed "Holy Prophet".

On Monday, Iran said it had tested a highly destructive torpedo, prompting the US State Department to voice "concern" at a time of high tensions over Iran's nuclear ambitions.

The series of armaments tests "demonstrates a weaponisation programme by Iran that does nothing to reassure Iran's neighbours or the international community", the State Department deputy spokesman said.
