An attack by Yemeni Houthi rebels late Thursday wounded 11 civilians in southern Saudi Arabia, the Riyadh-led coalition said, an unprecedented toll in the kingdom in over four years of hostilities.

They include seven Saudis, two Egyptians, a Yemeni, and a Pakistani, coalition spokesman General Turki al-Maliki said in a statement carried by the official Saudi news agency, adding that the attacks had taken place in the Najran region, on the border with Yemen.
