According to Yemeni security sources, the spy plane was shot down by the Yemeni’s air force in the mountainous regions of the province on Saturday.
An ensuing missile attack by Yemeni forces targeted a Saudi airbase in the kingdom’s southwestern Asir region.
Meanwhile, Yemeni troops carried out a retaliatory attack on a Saudi mercenary camp in the impoverished state's southwestern province of Lahij, destroying a tank and killing two soldiers.
At least 19 mercenaries fighting for Saudi forces were killed in an attack on the southwestern Ta'izz province. Some 13 others were also killed during an attack in the southwestern province of Dhale.
Earlier in the day, Yemen’s Defense Ministry announced that a Saudi Arabian F-16 jet was downed before landing at an airbase in the Lahij province.
Yemenis carry out these attacks in retaliation for Saudi strikes, launched with the aim of undermining Houthi Ansarullah movement and bringing back to power the country’s fugitive former president, Abd Rabbuh Mansur Hadi, a staunch ally of Riyadh.
