Rebels in Yemen advance on the port city of Aden despite airstrikes from a Saudi-led coalition. New evidence suggests the pilot of the Germanwings plane accelerated during descent. The Iraqi government declares victory over ISIS in its battle to take back Tikrit. And in Nigeria, a former general is elected president in the country’s first peaceful transfer of power.
