Yemen’s Ansar Allah, also known as the Houthis, launched significant strikes on Thursday targeting military camps in central Yemen belonging to the Emergency Forces, an anti-Houthi force recently created by Saudi Arabia that operates under the command of the Saudi military.

A military source within the Saudi-backed Yemeni government, whose leadership is based in Riyadh, told China’s Xinhua news agency that the Ansar Allah attacks targeted camps in the eastern Hadhramaut and Marib provinces and that at least 35 fighters were killed.
