RIYADH: Airstrikes took out a secret hideout housing experts belonging to the Iran Revolutionary Guard and Hezbollah in Yemen, the Arab coalition said on Thursday. Airstrikes hit targets in Sanaa, Dhamar, Saada, and Al-Jawf governorates in a wide-ranging operation by the coalition to weaken the Iran-backed Houthi militia. Warehouses in the capital, Sanaa, and Al-Dulaimi airbase were struck by coalition forces,  Al Arabiya TV said early on Thursday citing sources. Hours earlier the coalition blew up an explosive drone targeting Abha International Airport, in Saudi Arabia’s Asir province. The Kingdom is targeted on a near daily basis by Houthi militia in Yemen, who use explosive drones, which are hardly effective against Saudi air defenses. Flights were operating normally at the airport on Thursday, with no delays or cancellations reported. A Houthi drone targeted the same airport in October, leaving four workers with minor injuries caused by falling debris. On Wednesday, the coalition also destroyed two drones heading toward the southern Saudi city of Khamis Mushayt. The force also said it had carried out 29 operations targeting militias in Marib and Al-Bayda during the previous 24 hours, resulting in the destruction of a militia air defense system and left over 90 Houthis dead. Houthi actions against civilians has been condemned by the Kingdom’s leadership repeatedly, calling them tantamount to war crimes. The Arab coalition has been supporting the internationally recognized Yemeni government regain full control of the country after the Houthis seized the capital, Sanaa, in 2014. The resource-rich province of Marib has seen intense fighting between the Houthis and the Yemeni government. The militia, seeking to strengthen their control of the north with an advance into the region, has sustained heavy losses without much gain. On Wednesday, hundreds of Yemeni government troops were deployed to the central city of Marib to reinforce the soldiers and allied tribes fighting off the bloody Houthi offensive that is encroaching on the strategic location outside the city. Video footage on social media showed a long convoy of pickups, buses, and military vehicles carrying hundreds of soldiers who were chanting, “with our souls and blood, we will redeem you, Yemen,”  while heading to Marib. In March, Saudi Arabia announced a roadmap called the Riyadh Initiative to halt fighting in Yemen and reopen Sanaa airport, as well as continuing talks to find a solution to the conflict. The proposal was seen as a welcome step internationally, but has been rejected by Houthi leadership. The war, which has now lasted for seven years, has cost thousands of Yemenis their lives and has forced many more to depend on humanitarian assistance. Saudi relief agency, KSrelief, has poured billions of dollars worth of aid into Yemen and has hundreds of projects focusing on food and health.
