One soldier was killed and three others wounded on Wednesday in a live-fire military exercise between Pakistan and Saudi Arabia, official media said.
The Saudi Press Agency report did not specify which country the casualties were from.
It said “a non-commissioned officer has died and three other officers have sustained injuries during live-ammunition shooting related to the Saudi-Pakistani al Samsam 5″ exercises in Baha, in the kingdom’s southwest.
The incident occurred as the lawmakers debate whether or not to join a Saudi-led coalition aggression in neighboring Muslim state Yemen.
Saudi Arabia has asked its longstanding ally to contribute planes, ships and ground troops but the government has so far resisted.
The coalition on March 26 began air strikes against the Houthi’s revolutionists.
