In Yemen, the U.S.-backed, Saudi-led coalition bombed the main airport in the capital Sana’a Tuesday, damaging the runway and destroying navigation equipment. The attack came after Saudi Arabia shut air, land and sea routes into Yemen, drawing warnings from the United Nations that the clampdown could worsen Yemen’s massive cholera epidemic and set off the largest famine the world has seen in decades, with millions of victims. Tuesday’s attack drew condemnation from Connecticut Democratic Senator Chris Murphy, who tweeted, “The US/Saudi coalition took out the Sanaa airport last night. Now no humanitarian relief by air. This is barbaric.”
