RIYADH — The Arab coalition intercepted and destroyed another explosive-laden drone launched on Tuesday toward Saudi Arabia by the Iran-backed Houthi militia, the official Saudi Press Agency reported. Coalition spokesman Col. Turki Al-Maliki said the drone targeting civilians was intercepted and destroyed. The coalition has thwarted several attacks this month by the Iran-backed Houthi militia. The attacks were aimed at civilian infrastructure including Abha international airport. Cross-border attacks by Iran-aligned Houthi forces have escalated since late May, when a truce prompted by the coronavirus pandemic expired. In late June, missiles reached the Saudi capital Riyadh.
