Yemeni rebels have fired rockets and mortars into Saudi Arabia, killing at least two civilians and reportedly capturing five soldiers.

Saudi authorities say armed Houthi fighters carried out the attacks in the town of Najran, forcing the authorities to suspend all flights at a local airport, and shut down all schools.

In a statement, Saudi military commander Brig. Gen. Ahmed Asiri said the coalition forces will continue to respond to Houthi attacks, adding that all options are open to the kingdom to ensure its security.

News of the latest violence comes as Saudi King Salman announced at a meeting of Gulf leaders the establishment of a centre to coordinate relief operation in Yemen, and invited the United Nations to join in the effort.
