Saudi Arabia’s King Salman invited Gulf and Arab leaders to convene emergency summits to discuss the implications of this week’s attacks against the kingdom and neighboring United Arab Emirates, the foreign ministry said on Saturday.

The meetings are set for May 30 in Mecca, the ministry said on Twitter.

Four commercial ships were sabotaged off the coast of the United Arab Emirates on Sunday, and two days later drones attacked oil installations west of the Saudi capital Riyadh.
