Dubai: A United Nations aid official visiting both sides in Yemen’s civil war has urged them to guarantee more access to the country’s ports to let food, fuel and medicine imports in to ward off a looming famine.

Emergency relief coordinator Stephen O’Brien said the UN was urging international donors to step up their aid but the Yemenis had to ensure it could reach up to seven million people now facing severe food shortages.

Yemen has been divided by nearly two years of civil war that pits the Iran-allied Houthi group against a Western-backed coalition led by Saudi Arabia.

Nearly 3.3 million people in Yemen - including 2.1 million children - are acutely malnourished, the UN says. They include 460,000 children under age of five with the worst form of malnutrition, who risk dying of pneumonia or diarrhea.

Fighting in or near ports hampers access for aid coming from outside.

“The international community needs to step up its funding and the parties to the conflict need to continue providing humanitarian access,” O’Brien told reporters at the government’s base in Aden late on Monday.

“This also means access to the ports so that the needed imports can enter Yemen,” he said.

Earlier this month, the UN said air strikes on the Yemeni port of Hodeidah, which serves territory controlled by Al Houthis, had hampered humanitarian operations to import vital food and fuel supplies.

Five cranes at the port have been destroyed, forcing dozens of ships to lie offshore because they cannot be unloaded.

“Seven million people don’t know where their next meal is coming from and we now face a serious risk of famine,” O’Brien said.

O’Brien has also met with the Al Houthi movement in the capital Sana’a. On Tuesday, he was planning to visit the flashpoint city of Taiz but his convoy returned from its gates because of security concerns, a UN source told Reuters.
