Graffiti picturing a giant skull and a menacing snake have popped up on the walls of the shuttered Saudi embassy in Sanaa, Yemen’s capital. “A picture that speaks a thousand words” was the comment of quite a few Yemenis who shared photos of the graffiti on social media, criticizing Saudi Arabia for leading the coalition against Houthi rebels in Yemen.

Yemen has waded deeper and deeper into war since the Saudi-led coalition of Arab nations, backed by the United States, began bombing Houthi rebels in March to try to stop their expansion after they took Sanaa. Since then, air raids have led to the death of thousands of civilians . Most international organisations have by now left the country, and according to the United Nations, it is now experiencing a “ humanitarian catastrophe ”. Yemen was already one of the world’s poorest countries before war broke out.
