Saudi Arabia, Turkey and Pakistan will hold chief of staff talks to support the kingdom, Riyadh said in a statement on Friday, as Yemen's Houthis ramp up attacks on the world's top crude exporter.

The Iran-backed group has escalated its attacks on the kingdom since July, ending a years-long truce and declaring a maritime blockade, hitting Saudi targets and seizing Yemen's entire Red Sea coast as they seek to stifle Saudi oil exports.
