On 5 December 2013, a coordinated terrorist attack occurred targeting the Ministry of Defense complex in Sana'a, Yemen. Heavily armed militants utilized a car bomb to breach the gates of the complex before storming it and occupying a hospital within it. The attack, which killed 52 people and injured 167, was claimed by Ansar al-Sharia, an affiliate of al-Qaeda in the Arabian Peninsula (AQAP). AQAP later issued an apology for the attack after footage from within the hospital was broadcast showing the gunmen murdering medical personnel.
