The Battle of Zinjibar was a battle during the 2011 Yemeni Revolution between forces loyal to Yemeni leader Ali Abdullah Saleh and Islamist militant forces, possibly including elements of al-Qaeda in the Arabian Peninsula (AQAP), for control of the town of Zinjibar and its surroundings as part of the wider insurgency in the self-declared Al-Qaeda Emirate in Yemen. Many of the Islamist forces operating in Abyan province refer to themselves as Ansar al-Sharia ("Partisans of Sharia").
