Yemen tribes attack Saudi military post and using weapons to launch attacks on Saudi cities

Yemen's rebels fired rockets and mortars into Saudi Arabia on Tuesday, killing at least three people and purportedly capturing five soldiers in an attack showing the insurgents' ability to launch assaults despite weeks of Saudi-led airstrikes targeting them.

Saudi Arabia's national airline cancelled flights into the border area of Najran as schools closed early amid the attack, the first by the rebels, known as Houthis, to target a civilian area in the kingdom since the start of the airstrikes late March. Meanwhile, hundreds of families fled the southern Yemeni city of Aden after the Houthis advanced into their neighborhoods, firing indiscriminately as they took over surrounding, towering mountains.

In the Saudi area of Najran, the Houthi shelling killed two Saudi civilians and damaged buildings, Yemeni tribal leaders said. The official Saudi Press Agency carried an Interior Ministry statement saying three people had been killed, though it did not specify if they were all civilians.

The national airline, Saudia, said flights to and from the area would be suspended until further notice, without elaborating. It is the only carrier flying to Najran. Saudi state television reported local schools closed early and aired footage showing cars burnt, smoldering houses and debris covering nearby roads.

The tribal leaders, who spoke on condition of anonymity for fear of reprisals, also said the Houthis captured five Saudi soldiers in unclear circumstances.

Saudi Brig. Gen. Ahmed Asiri said that Saudi-led coalition forces continue to respond to the Houthi attack.
