Yemeni leader steps down
Agrees to end 33-year reign; power shifts to vice president
After months of street protests calling for his resignation, President Ali Abdullah Saleh signed an agreement yesterday that Yemeni officials said immediately transferred power to his vice president. The agreement effectively ends Saleh’s 33 years of authoritarian rule, making him the fourth leader forced from power by the Arab Spring revolts that have roiled the Middle East and North Africa. But it is unlikely to restore calm anytime soon to a country that has become increasingly important to the United States as Islamist militants have gained a stronger hold there.
