"Bahrain said on Sunday it had broken up a banned anti-government Shi'ite Muslim group behind a series of attacks and arrested several of its members," reports Reuters .
"Sunni-ruled Bahrain accuses Shi'ite Muslim Iran of fomenting unrest among Bahrain's mostly Shi'ite opposition. Iran denies the accusation, but does champion the Shi'ite majority's cause."
"Bahrain, home to the U.S. Navy's Fifth Fleet, was rocked in 2011 by protests demanding greater democracy and more rights for Shi'ites, many of whom say they are subject to political and economic discrimination. Despite a heavy crackdown on protest, sporadic bursts of unrest by Shi'ites continued for more than two years, though these have now largely subsided."
