Jihadi John, Kuwaiti-British member of ISIS (died 2015)

Mohammed Emwazi was a British militant of Kuwaiti origin seen in several videos produced by the Islamist extremist group Islamic State (IS) showing the beheadings of a number of captives in 2014 and 2015. A group of his hostages nicknamed him "John" since he was part of a four-person terrorist cell with English accents whom they called 'The Beatles'; the press later began calling him "Jihadi John".

The Islamic State (IS), also known as the Islamic State of Iraq and the Levant (ISIL), the Islamic State of Iraq and Syria (ISIS) and Daesh, is a transnational Salafi jihadist militant organisation and was a unrecognised quasi-state. IS occupied significant territory in Iraq and Syria in 2013, but lost most of it in 2017 and 2019. In 2014, the group proclaimed itself to be a worldwide caliphate, and claimed religious and political authority over all Muslims worldwide, a claim not accepted by the vast majority of Muslims. It is designated as a terrorist organisation by the United Nations and many countries around the world, including Muslim countries.
