The number of people in need as a result of Yemen's conflict continues to rise, but the international aid response has failed to keep up. International donors should immediately commit to fully funding the Yemen Humanitarian Response Plan. As the tables in this briefing show, some donor governments are pulling their weight, while others are not. Aid alone, however, cannot solve Yemen's crisis or put the country back on its feet. All sides and their international backers should stop the de-facto blockade and the conflict that are pushing Yemen towards famine.
