Yemen is in a very fragile state. After 33 years of rule, president Ali Abdullah Saleh let go of power in February 2012, and the nation entered a two-year transitional period intended to steer it towards democracy and stability. His successor,Abd-Rabbu Mansour Hadi, has inherited a nation beset by violence and competing factions. A smouldering insurgency in the north, secessionism in the south, a powerful jihadist movement and remnants of the old guard are all high on the agenda.
