Here is a look at Sunni extremist group Al Qaeda in the Arabian Peninsula (AQAP).
The Yemeni-based arm of al Qaeda, AQAP, emerged when al Qaeda in Saudi Arabia and Yemen unified in 2009.
Many analysts believe AQAP is the most dangerous al Qaeda affiliate.
AQAP’s main goals include establishing a caliphate in the Arabian Peninsula, implementing Sharia law and targeting local, US and Western interests in the Arabian Peninsula and worldwide. AQAP has targeted multiple embassies, as well as foreign tourists, using car bombs and suicide bombs.
The State Department estimates AQAP’s membership to be in the “low thousands.”
Anwar al-Awlaki served as the spokesman for AQAP until his death in 2011.
Nasir al-Wuhayshi, the No. 2 leader in al Qaeda globally, served as the leader of AQAP until his death in 2015.
Al-Wuhayshi was succeeded by AQAP’s military commander, Qassim al-Rimi.
AQAP is funded through robberies and kidnappings, as well as through donations from supporters.
In an effort to rebrand, AQAP has sometimes gone by the alias Ansar al-Sharia (AAS), which means “supporters of Islamic law.” However, numerous groups have taken on the name Ansar al-Sharia, and not all are associated with AQAP.
