Ansar al Sharia (Yemen)

Jama'at Ansar al-Shari'a (Arabic: جماعة أنصار الشريعة‎‎; Jamāʿat Anṣār aš-Šharīʿa), also known as Ansar al-Shari'a, is a Yemen-based umbrella organization which includes units from several militant Islamic groups of al-Qaeda in the Arabian Peninsula (AQAP). In 2011, AQAP created Ansar Al-Sharia as a Yemen-based affiliate focused on waging an insurgency rather than international attacks on the West. In the view of the International Crisis Group, AQAP is "an internally diverse organisation with varying layers of support among the local population" and many AAS members and allies are not committed to AQAP's international agenda.

After the Battle of Zinjibar (May–September 2011), the faction had taken control over some cities in southern Yemen in which it has instated emirates. Ansar ash-Shari'a have also claimed responsibility for the 2012 Sana'a bombing and the 2013 Sana'a attack. As of early 2017, AQAP and AAS were currently in a struggle for territorial control with the Houthi/Saleh forces in the governorates of al-Bayda, Shebwa, Marib, Jawf and Taiz.

On 4 October 2012, the United States Department of State amended its list of Foreign Terrorist Organizations to designate Ansar al-Sharia in Yemen as an alias for al-Qaeda in the Arabian Peninsula, rather than listing it as a separate organisation. On the same day, the group was also listed by the United Nations 1267/1989 Al-Qaida Sanctions Committee. New Zealand also listed it as a terror group.

In February 2015, it was reported that some members had split from the group and pledged allegiance to the Islamic State of Iraq and the Levant.
