In Yemen, three people were killed Monday after a drone crashed into a residential neighborhood in the capital Sana’a. Witnesses said the Saudi-led coalition drone was shot down by Houthi rebels as it circled the skies over the capital.

Youssef Hamiduddin: “Unfortunately, it fell on citizens. This is a commercial market, and these are street vendors. The spy drone fell on them. And this is a violation of the two-month truce in Yemen.”

The United Nations is calling on Yemen’s Houthi rebels and the Saudi-led coalition to extend the ceasefire, which is due to expire on June 1. The World Food Programme says five years of continuous war in Yemen has sparked the world’s worst humanitarian crisis, with about two-thirds of all Yemenis — or some 20 million people — suffering from hunger and malnutrition.
