Mid morning yesterday, no less than 5 suicide bombers entered a predominantly Shia mosque in the city of Saan’a. According to eyewitness reports, the first bombers detonated their explosives amongst the crowd of Houthi worshippers, and then, just as the survivors began to flee, a final bomber set off his bomb vest, killing many more. In total 142 people were murdered, and several hundred more injured. It was the worst attack so far in Yemen’s new civil war. Yemen’s collapse into war has been a long time coming. The country has faced severe instability since the Arab Spring in 2011, at risk of being torn apart by Shia Houthi Rebels in the north, separatist fighters in the south, and Al Qaeda Sunni extremists in the east. Despite this, the government of Abd Rabbuh Hadi had managed to hold on to power, after making large amounts of concessions, and even turning the country into a federation.
