Bosnian mujahideen (Bosnian: Bosanski mudžahedini), also called El Mudžahid (from Arabic: مجاهد, mujāhid), were foreign Muslim volunteers who fought on the Bosniak (Bosnian Muslim) side during the 1992–95 Bosnian War. They first arrived in central Bosnia in the second half of 1992 with the aim of helping their Bosnian Muslim co-religionists in fights against Serb and Croat forces. Initially they mainly came from Arab countries, later from other Muslim-majority countries. Estimates of their numbers vary from 500 to 6,000.
