The World Food Program (WFP) and Yemen's Houthi movement, which controls the capital Sanaa, have said they had reached a deal that could lift the U.N. agency's partial suspension of aid that has affected around 850,000 people.

The U.N. agency halted some aid in Sanaa on June 20 out of concern that food was being diverted from vulnerable people, but said it would maintain nutrition programs for malnourished children, pregnant and nursing mothers.

The warring parties in Yemen's conflict have both used access to aid and food as a political tool, exacerbating what the United Nations has called the world's worst humanitarian crisis. Of Yemen's 30 million people, three-quarters need humanitarian assistance.
