Yemen: Months of unrest and turmoil

Yemen is a poor, deeply divided country in turmoil since January 2011, when mass demonstrations called for President Ali Abdullah Saleh to resign. Saleh has been in power since 1978. Demonstrations have continued for months and Saleh's support has crumbled as some army commanders and tribal leaders have called for his ouster. On April 7, an organization of oil-rich Persian Gulf states joined the increasing number of international voices calling for a transfer of presidential powers. Protests and deadly clashes continue daily with security forces and rival military factions allied with the government and the rebels. More than 100 protestors have died since the turmoil began. -- Paula Nelson
