At least 370,000 people have already died in the Yemen conflict, while millions have been displaced. The United Nations ranks the bloody proxy war and its effects as the world's worst humanitarian crisis. The conflict in Yemen, in the south of the Arabian Peninsula, has been going on for years, and has recently seen renewed intensity. In January, an airstrike by the Saudi-led coalition on a prison in the north of the country killed at least 70 people and left hundreds injured.
