That didn’t last long: A truce between the Yemeni government and tribal groups signed just a few days ago is already over. Reuters reported that more than 20 people were killed in Sanaa overnight. "The ceasefire agreement has ended," a government official said Tuesday. The return to violence renews fears of outright civil war. In Yemen’s second-largest city, Taiz, police have killed more than 50 protesters since Sunday.
