Repeated warnings of the effects of the war in Ukraine on developing countries reached a new pitch on 13 April, when UN humanitarian agencies said that millions of displaced families across eastern Africa will fall deeper into hunger, as food rations dwindle, amid a lack of sufficient funds, meaning more than 70 percent of refugees in need do not receive enough to eat.

And that same day, the Secretary-General, António Guterres, launched a report detailing the disastrous consequences of the Ukraine war for those who rely on grain supplies sourced from the country.

Joyce Msuya, the UN’s deputy emergency relief chief, joined us in our UN News studio and told Conor Lennon that she had noticed back in 2021 that the hunger crisis was growing - well before the Russian invasion began.
