Arab Gulf states pledged on Thursday to fight “terrorism” and “foreign interference” across the region.

In a joint statement following a summit in Riyadh, interior ministers of the six-nation Gulf Cooperation Council said they were determined to prevent “harm to their national unity, the provoking of sectarian tensions and support for terrorist groups”.

The GCC states regularly accuse Iran of interfering in their internal affairs, particularly of stirring unrest in Bahrain and supporting Shiite rebels in Yemen — charges Iran denies.

They said GCC states had shown determination to build bridges of cooperation with other states in the region.

“The biggest challenge facing any state in the modern world is preserving its national unity against foreign and domestic threats,” said Saudi Crown Prince and Interior Minister Mohammad Bin Nayef, who chaired the summit.
