Yemen is running critically short of imported food and fuel as war has cut internal supply lines and a near-blockade by Saudi-led naval forces has held up shipping to the country.
The United Nations says that more than 80 percent of its 25 million people need some form of emergency aid.
Before Saudi Arabia intervened in March to try to restore Yemen’s president to power, Yemen imported more than 90 percent of its food, mostly by sea.
Since then, many shipping companies have pulled out. Those still willing to bring cargoes face incalculable delays and mandatory searches by coalition warships hunting for arms bound for the Houthis, the dominant warring faction.
