UNITED NATIONS, Sept. 21  - UN Under-Secretary-General for Humanitarian Affairs Mark Lowcock on Friday warned of the danger of widespread famine in Yemen.

"The Security Council has asked for an update today on the humanitarian situation in Yemen. In a word, it is bleak," said Lowcock. "We are losing the fight against famine."

The situation has deteriorated in an alarming way in recent weeks, he told the Security Council. "We may now be approaching a tipping point, beyond which it will be impossible to prevent massive loss of life as a result of widespread famine across the country."

Some 18 million of the 29 million Yemenis, including a high proportion of children, are food insecure, and more than 8 million of them severely food insecure, meaning they do not know where their next meal will come from and they need emergency food assistance to survive, according to Lowcock.
