A wounded supporter of Yemen's president is seen crawling, then being dragged to safety under intensive gunfire on 7 April, according to video filmed by one of the man's colleagues.

The colleague, a member of the Popular Committees militia, fighting for President Abd-Rabbu Mansour Hadi in the southern Yemeni city of Aden, said it showed the wounded comrade being pulled out of the line of fire.

The Saudi-led air campaign to reinstate Hadi has failed to stop Iran-allied Houthis fighters, who already control the north of the country and Yemeni capital Sanaa, from pushing into the heart of Aden.

Saudi-backed Hadi was forced to flee Aden late last month after Sanaa fell under Houthi control.

Saudi Arabia and four other Gulf Arab states, along with regional allies, have waged two weeks of air strikes against Houthi forces. This has helped to push back Houthis and their allies from some of their positions in parts of some southern provinces.
