Border guards also arrested two suspects during the incident on Friday, said General Mohammed Zahrani, the chief of border guards in the southern Saudi border city of Najran, according to the official SPA news agency.
The guards seized more than 1.2 tonnes of hashish, automatic weapons, munitions and military uniforms which the suspects had hidden in their car, SPA quoted Zahrani as saying.
