The Saudi navy has detained three members of Iran's Revolutionary Guard Corps (IRGC) from a boat seized on Friday evening as it approached the kingdom's offshore Marjan oilfield, a Saudi Information Ministry statement said on Monday. 'This was one of three vessels which were intercepted by Saudi forces. It was captured with the three men on board; the other two escaped,' said the statement from the ministry's Center for International Communications. 'The three captured members of the Iranian Revolutionary Guard are now being questioned by Saudi authorities.'
