The Bahrain Freedom Movement (Arabic: حركة أحرار البحرين الإسلامية, romanized: Harakat Ahrar al-Bahrayn) is a London-based Bahraini opposition group which has its headquarters in a north London mosque. Its main medium is the Voice of Bahrain website which was blocked for several years by Batelco, Bahrain's sole Internet service provider, on orders from the Ministry of Information. The BFM played a leading role in the 1990s uprising in Bahrain.
