Abu Rumaysah al-Britani (born 24 June 1983, died 2017), born Siddhartha Dhar, was a Bengali origin British Citizen turned Islamic State of Iraq and the Levant (ISIL) militant and Jihadi. A Muslim convert from Hinduism, he belonged to a Bengali family of expatriates from India. In January 2016, he was named as the narrator in a film issued by ISIL that showed the execution of suspected spies against the regime. Abu Rumaysah was designated as a global terrorist by the United States. He and his family are believed to have been killed on the battlefield by a drone strike in 2017.
Dhar was born in London to a Bangla-speaking Hindu family of Indian extraction and changed his name to Abu Rumaysah after his conversion to Islam. He acted as a spokesperson for the Islamist group Al-Muhajiroun, an organisation banned in the UK, and worked as an aide to Al-Muhajiroun's co-founder, Anjem Choudary. Dhar also owned a bouncy castle rental company. He lived in Walthamstow. He used social media to promote his radical Islamist views and attended demonstrations in Britain against the United States, Israel, and Arab regimes. In a video he posted to YouTube, Dhar described ISIL's self declared caliphate as "...a dream for all Muslims worldwide ... We can finally have a sanctuary where we can practice our religion and live under the Sharia. It is a big, big thing".
He spoke of his desire for the United Kingdom to be governed under Sharia law on the BBC's Sunday Morning Live programme, and said of himself that he didn't "...really identify myself with British values. I am Muslim first, second and last". In 2014, Dhar was under investigation by British authorities for allegedly encouraging terrorism, but subsequently disappeared after being released on bail. Although he had been banned from travelling, Dhar departed for Paris from Victoria Coach Station in London with his wife, Aisha, and their four children, and later arrived in Syria. Dhar was believed to have been living in Raqqa as of September 2015.
Dhar wrote a travel guide to the Islamic State in May 2015, called A Brief Guide to Islamic State, and wrote of it that "If you thought London or New York was (sic) cosmopolitan, then wait until you step foot (sic) in the Islamic State because it screams diversity. [...] In my short time here I have met people from absolutely every walk of life, proof that the caliphate's pulling power is strong and tenacious".
