In response to questions from the floor, Brig. Gen. Asiri denied any resistance by Houthi militia to the air operation. On the possibility of a ground forces operation to repel the Houthi concentrations heading for the Southern border of the Kingdom, he said the Saudi ground forces are currently evaluating the situation on the ground, using field artillery and Apache aircraft to respond to the situation accordingly. About reports on a crash of an F-15 in the Red Sea, he attributed the incident to a technical fault, confirming the safety of the pilots, citing one as already returned to work and the other sustaining hand injury and drawing attention to the possibility of losses in any military operation. Asked on the progress of Houthi militias towards Aden, he said the "determination storm" operation is being implemented according to a timetable to achieve its goals, noting that the coalition forces are facing militias which moves in individuals and light groups among residents and not organized army, requiring the coalition to exert greater effort to remain committed to not harm civilians. In this regard, we continue assessing the situation, he said. On the delay of evacuating UN personnel from Sanaa, he said the alliance gave the okay to the planes to pick them, but the Houthi militias on the ground are the ones who caused the delay. --More 23:52 LOCAL TIME 20:52 GMT www.spa.gov.sa/w
