Saudi-led coalition redoubles attacks

The fight in Yemen has escalated dramatically over the past week, exacerbating a dire humanitarian crisis that the United Nations says could spiral into famine — despite, or even because of, a diplomatic push by the United States to get both sides to the peace table. The Saudi-led coalition, which the United States has armed and supported, has launched a punishing wave of airstrikes against the rebel Houthis. The warplanes have hit targets in the capital, Sanaa; and in the Red Sea port of Hodeida where, aid workers warn, the country’s main humanitarian lifeline hangs by a thread.
