The Saudi navy seized a boat carrying weapons as it approached the kingdom's offshore Marjan oilfield in the Gulf on Friday evening, SPA reported on Monday.
Two other boats that also approached Marjan managed to escape after the Saudi navy fired warning shots, the agency reported. The captured boat was carrying weapons "for subversive purposes", the report said.
SPA had no word on the registration of the vessels or the nationality of the crew, but added that the vessels were bearing white and red flags.
The kingdom stressed determination to combat and eradicate terrorism, protect national security and thwart any external aggression, Sabq newspaper added.
