The United Nations and humanitarian aid agencies launched the 2025 Humanitarian Needs and Response Plan (HNRP) for Yemen on Wednesday, appealing for US$2.47 billion to provide urgent humanitarian assistance to 10.5 million people in need. More than half of the country's population - 19.5 million people - are in need of humanitarian assistance and protection this year, with Yemen's most vulnerable and marginalized groups, including women and girls, at greatest risk.
