A government statement Saturday alleged the 54-member group went to Iraq and Iran to "receive training in the use of explosives and firearms at Revolutionary Guard camps." It said police seized firearms, bombs, cars, boats and a drone.
The statement linked the group to a series of attacks, including a January prison break. It said the group's leader was in Germany, without elaborating.
Iran's government had no immediate comment. Sunni-ruled Bahrain, like other Gulf Arab nations, remains suspicious of Shiite power Iran.
