The Middle Eastern country of Yemen is close to entering its fourth year of civil war, which has become a proxy conflict for Iran and Saudi Arabia. The United States has supported Saudi Arabia with weapons sales and logistics. The Saudi coalition fighting in the country has caused an estimated 15,000 civilian deaths from aerial bombing, and its blockade of the country has pushed some 20 million people to the brink of famine. 85,000 children are already estimated to have died from hunger. The UN has warned that the worst famine in a century could break out.
