DUBAI: Yemen’s army shot down the fourth Houthi drone in March while it was in Nihm district of the Sanaa governorate airspace, Saudi news agency SPA reported on Saturday. This is the seventh drone the army shoots down in Nihm since the start of the year, sources said. Earlier this month, the Saudi-led Arab coalition raided two caves in Sanaa used by Houthi militants to store drones. Coalition spokesperson Colonel Turki Al-Malki said the militia was planning to use the drones hidden in the caves for “terrorist operations.” Last week’s raid was part of previous military operations which started in January and targeted Houthi drone networks and foreign experts helping the militants. Meanwhile, Houthi militants executed a civilian in Hajjah province after he refused to let them position their tank in his backyard.
