NAJRAN: The Saudi-led coalition battling Houthi forces in Yemen said on Thursday it had intercepted and destroyed several explosive-laden drones aimed at Saudi Arabia, state TV reported.

The coalition said the Iran-aligned Houthis attempted to target universities in both Najran and Jazan, Saudi cities near the Yemeni border. The coalition said it had destroyed the one targeting Najran, as well as six additional explosive-laden drones fired by the Houthis aimed at the kingdom.

On Friday, the Houthi group said it had launched attacks against several Saudi Aramco facilities and military sites in the kingdom.

Houthi military spokesman Yahya Sarea said on Twitter that the group had targeted King Abdelaziz military base in Dammam and military sites in Najran and Asir. Sarea also said they targeted Aramco facilities in Ras al-Tanura, Rabigh, Yanbu and Jizan.

Saudi Arabia’s energy ministry said one of the projectiles struck a petroleum products distribution station in Jazan that resulted in a fire in a tank, state news agency SPA reported. There were no casualties, the ministry said.

When contacted by media, Saudi oil giant Aramco said it would respond at the earliest opportunity.

The kingdom’s defence ministry said Saudi Arabia would take deterrent actions to protect oil exports following the attacks, Saudi news agency SPA reported.

The drone attacks took place days after Riyadh presented a new peace initiative that includes a nationwide ceasefire.

The Houthis have recently stepped up drone and missile attacks on Saudi Arabia, including on oil facilities, and a ground offensive to seize Yemen’s gas-rich Marib region.

The coalition has responded with air strikes on Houthi military sites.

Yemen has been mired in war since the Saudi-led coalition intervened in March 2015 after the Houthis ousted the internationally recognised government in the capital Sanaa.

The conflict is widely seen in the region as a proxy war between Saudi Arabia and Iran. The Houthis, who now control most of northern Yemen, deny being puppets of Iran and say they are fighting a corrupt system and foreign aggression.
