Yemen, one of the world's poorest countries and a crucial US ally in Washington's fight against al-Qaeda, is in the midst of a series of conflicts that threaten its stability.
As well as tackling al-Qaeda fighters and dealing with a growing secessionist movement in the south, the government is also trying to cement a truce with Houthi rebels, who are primarily from the Zaidi Shia sect of Islam, in the north.
Below is an outline of security developments in the past months, categorised as being related to the Houthi rebels (N Yemen), southern secessionists (S Yemen) or Al-Qaeda in the Arab Peninsula (AQAP).
