The Houthi movement is an armed Islamist terrorist organisation based in Yemen. A large Zaydi Shia clan originating from Yemen’s northern Saada province, the group originally sought to revive Zaydi traditions in Yemen in opposition to Salafi influence from neighbouring Saudi Arabia in the 1980s and 1990s.

AQIM is a Salafi-Jihadist organisation that aims to overthrow governments in Algeria, Morocco, Tunisia, and Mali and the establishment of an Islamic Caliphate. The group’s attacks have shown significant interest in targeting security forces of these countries. Foreign nationals, particularly those from countries such as France and the US, continue to be a high priority of the group.

The Islamic State of Iraq and the Levant, known by its Arabic acronym Daesh in Khorasan - or Daesh-K, named after an old term of the region, is an affiliate of the Islamic State of Iraq and the Levant (ISIL) active in South Asia and Central Asia. First appearing in Afghanistan in late 2014, the group announced its expansion to the Khorasan region in 2015, which encompasses parts of Iran, Central Asia, Afghanistan, and Pakistan.
