Saudi Arabia has called for urgent meetings of the regional Gulf Cooperation Council and the Arab League to discuss escalating tensions in the Gulf.
The Saudi Press Agency said King Salman had invited gulf leaders and Arab states to two emergency summits in Makkha on May 30 to discuss recent "aggressions and their consequences" in the region.
Tensions have soared in the gulf with the U.S. Deploying an aircraft carrier and bombers to the region over alleged threats from Iran.
Four ships including two Saudi oil tankers were damaged in mysterious sabotage attacks off Fujairah, an emirate located at the crucial entrance to the Gulf.
That incident was followed by drone strikes by Yemen's Huthi rebels on a major Saudi oil pipeline, which provided an alternative export route if the strait of Hormuz closed.
