The Saudi-led coalition has deployed newly formed units near Yemen’s Marib where battles have subsided.
The Iran-aligned Houthi movement last month responded to losses in Shabwa and Marib at the hand of Emirati-backed forces.
Marib is vital because it is the internationally recognized government’s last stronghold in North Yemen, and the country’s sole gas producing region with one of its largest oilfields.
The coalition in January sent the Giants Brigade to main front lines after Houthi advances following years of stalemate, during which the UAE in 2019 largely reduced its presence.
