More than three years into a civil war, Yemen now faces one of the worst humanitarian crises in the world. The fighting there began in 2014, when Houthi rebels opposing Yemeni government corruption took over large swaths of the country. But since then, the conflict has turned into a proxy war between the predominantly Shiite Houthis, who are backed by Iran, and the largely Sunni government of Yemen, which is backed by Saudi Arabia. Both sides have used food as a tool of war, which has left much of Yemen's population on the brink of famine and in desperate need of aid. NewsHour Weekend Special Correspondent Marcia Biggs reports.
