Approximately three-quarters of JeM's membership is drawn from Punjab in Pakistan, from Multan, Bahawalpur and Rahim Yar Khan districts. This region being the main ethnic origin of the Pakistani military corps, ISI believed that the shared ethnicity would make the JeM aligned to the military's strategic goals. There are also a large number of Afghans and Arabs. Several western militants of Pakistani origin have also joined the organisation. Prominent among them are Rashid Rauf, who was involved with a 2006 plot to blow up transatlantic airliners, Shehzad Tanweer, who was involved with the 2005 London Underground bombings, and Ahmed Omar Sheikh, convicted of murdering Daniel Pearl.
