U.N. Warns Millions at Risk in Yemen, Urges Saudi Coalition to Open Ports

"We have some 21 million people needing assistance and seven million of those are in famine-like conditions and rely completely on food aid," U.N. humanitarian coordinator for Yemen Jamie McGoldrick said.

"The continued closure by the Saudi-led coalition of critical seaports and airports is aggravating an already dire humanitarian situation. I think it poses a critical threat to the lives of millions who are already struggling to survive."

McGoldrick was speaking to reporters in Geneva by phone from Amman, because he said flights into Sanaa were blocked.
