In Yemen, the governor of Taiz says the city of roughly 1 million people has entered into famine due to a weekslong siege by fighters with the Ansar Allah movement, known as the Houthis. Human Rights Watch said Thursday the siege could amount to the war crime of using starvation as a method of warfare. The famine declaration came as a Saudi airstrike on Taiz killed 13 people. That followed a Houthi attack on Aden’s airport that injured passengers and halted flights. Meanwhile, the Houthis are rejecting claims by the Saudi-led coalition that Saudi air defenses intercepted missiles fired toward Mecca.
