RIYADH — The Gulf unity and the continuation and success of the Gulf Cooperation Council (GCC) are top concerns for Custodian of the Two Holy Mosques King Salman, the head of Saudi Arabia's Shoura Council, Abdullah Al-Sheikh, said on Monday. In a statement carried by the Saudi Press Agency Al-Sheikh also stressed that the invitation of King Salman to the GCC leaders comes amid exceptional circumstances the region is facing, which require cooperation among the member states and strong joint action. The Shoura Council chief also praised the efforts of Crown Prince Muhammad Bin Salman, under the direction of King Salman, to strengthen the GCC and maintain its unity, security, stability, and cohesion. "The region suffers from turmoil in view of the foreign interference in the affairs of the countries of the region, threatening the close and historic relations among the member countries and their people," he said.
