David Beasley, the head of the World Food Program, is currently in Afghanistan in a race against time to deliver emergency aid to hundreds of thousands of people.

In a video message posted on Twitter Thursday, Beasly said: We’re here in Afghanistan where the world’s worst humanitarian crisis is unfolding.

He said WFP is scaling up operations and making sure humanitarian aid and supplies reach those in need.

We’re ready to do even more. But, we urgently need $230 million per month to reach 22 million-plus people with life-saving food, he said.

Speaking from Kabul airport, Beasley said flights carrying aid and aid workers were being despatched to other parts of the country, including Kandahar.

UN agencies say as many as 22.8 million people - more than half of Afghanistan’s 39 million population - are facing acute food insecurity, compared to 14 million just two months ago.
