Fighters of Yemen’s Houthi Ansarullah movement and military units have killed more than two dozen mercenaries fighting for Saudi Arabia in Yemen. Yemen’s al-Masirah TV said on its twitter account on Saturday that at least 25 mercenaries were killed after the allied Yemeni forces launched an offensive on their positions in Jad’an region of the northern province of Ma’rib. The report did not elaborate on the nationality of those killed. Saudi Arabia and some Arab governments in the Persian Gulf region, which have been contributing to Riyadh’s more than 300 days of airstrikes and ground operations against Yemen have recruited troops from various nationalities for the war on Yemen. Previous reports had suggested that thousands of troops and security forces, from Latin American and Asian countries, have been fighting in Yemen. Masirah said the mercenaries were killed while advancing along a road to the northern province of Jawf, adding that Saudi Arabian warplanes conducted more than 100 airstrikes in the area to facilitate the advance of the ground forces. The Houthis and allies also continued to carry out attacks against military positions south of Saudi Arabia, with reports saying that gatherings of Saudi soldiers were targeted east of the city of al-Rabuah in the province of Asir. There was no immediate claim by Yemenis of inflicting casualties on the Saudis during the operation. Attacks were also launched on Saudi positions in Jizan where a number of soldiers were reportedly killed in al-Qawiyah and al-Dokhan regions. The Yemeni forces also targeted Saudi bases in Alib and Haras al-Hodud regions in Najran Province, Masirah said. More than 8,300 people have been killed and hundreds of thousands have been displaced since Riyadh launched its deadly campaign in late March 2015.
