According to Yemeni media reports, the Arab country’s air defense forces targeted the surveillance aircraft with a surface-to-air missile on Monday morning.
The drone was shot down over al-Shajan village, the reports added.
In a separate development, at least three civilians were killed and another sustained injuries when militiamen loyal to the country’s former president, Abd Rabbuh Mansur Hadi, shelled a residential neighborhood in the southern province of Ta’iz despite a two-week ceasefire declared by the Saudi-led coalition.
Local sources, speaking on condition of anonymity, told Arabic-language al-Masirah television network that the Saudi mercenaries fired projectiles at Wadi Hanash village in the At Ta'iziyah district of the province Sunday afternoon.
The sources added that two women and a child were killed whilst a man was injured when their house was struck in the shelling.
Saudi Arabia and a number of its regional allies launched a devastating campaign against Yemen in March 2015, with the goal of bringing the government of Hadi back to power and crushing the Houthi Ansarullah movement.
The US-based Armed Conflict Location and Event Data Project (ACLED), a nonprofit conflict-research organization, estimates that the war has claimed more than 100,000 lives since then.
