Yemen, an impoverished Arab country, has been gripped by one of the most active regional al-Qaeda insurgencies in the Middle East.

The Yemen-based al-Qaeda in the Arabian Peninsula (AQAP), also known locally as "Ansar al-Sharia," emerged in January 2009, has claimed responsibility for a number of terrorist attacks against Yemen's army and governmental institutions.

The AQAP and the IS-linked militants took advantage of the security vacuum and ongoing civil war to expand their influence and seize more territories in southern Yemen.

Security in Yemen has deteriorated since March 2017, when war broke out between the Shiite Houthi group, supported by former President Ali Abdullah Saleh, and government forces backed by a Saudi-led Arab coalition.

Over 10,000 people have been killed in ground battles and airstrikes since then, many of them civilians.
