Yemeni children are suffering acute malnutrition at unprecedented rates as the world’s worst humanitarian crisis grinds on and funding falls far short of what is needed to offset the effects of conflict and  economic collapse, UN agencies said in a statement on Tuesday.  

An “airlift of hope” agreed by Yemen’s warring parties to return more than 1,000 detainees to their families has been welcomed by UN Special Envoy Martin Griffiths, who has urged both sides to agree to further peace-building measures.

At the end of a week-long meeting in Switzerland, the parties to the conflict in Yemen reached what the UN envoy there called “a very important milestone”, in agreeing to release a first group of detainees.

Working from a field office in Yemen, Sonia Almassad ensures that UN relief aid reaches those who need it, in the war-torn country. She was previously posted in her home country, Syria, where she negotiated with armed groups on both sides of the conflict, sometimes at great personal risk.
