RIYADH — Houthi militias, who shelled on Tuesday some schools and a field hospital in Najran city, will not go unpunished, asserted Brig. Gen. Ahmad Al-Asiri, spokesman of the coalition forces and adviser at the office of the minister of defense. “Air and ground forces will respond in the right way to these hazardous acts and will not allow them to be repeated,” Asiri said. The Saudi military had already deployed Apache combat helicopters to target the rebels in the border area, he added. There were some injuries in the attack on the hospital, Asiri added. “These rebels have come to the border with suicide missions and they will be destroyed,” he said, adding that the situation on the border is totally under control and the Armed Forces are geared up to ensure full security and stability along the borders. All schools and university faculties were closed and Saudi Arabian Airlines suspended flights to and from Najran airport. “The armed forces are carrying out their duties in confronting the aggression by Houthis and today's action will not pass without punishment. “What happened today reflected the state of chaos the Houthis are in after nearly six weeks of airstrikes.” The Al-Ekhbariya network showed images of buildings and cars damaged in the attack. According to Al-Watan daily, one of the mortar shells struck the office of the newspaper's director in Najran. Saleh Al-Siwan, the director, and his family members escaped unhurt and they were in good condition.
