Amnesty International has released a new report detailing what it calls a “chilling crackdown on dissent” in the U.S.-backed Gulf kingdom of Bahrain. Despite promises of reforms, Amnesty reports rampant abuses, including torture, arbitrary detention of human rights activists and excessive force against protesters have continued in Bahrain, following a 2011 uprising against the Sunni monarchy. The report comes as Bahrain hosts the Formula One Grand Prix auto race. Bahrain is a close ally of the United States, home to the Navy’s Fifth Fleet.
