A 20-year-old woman who recited poems critical of Bahrain’s rulers — and later claimed she was beaten in jail — was sentenced Sunday to a year in prison as part of the kingdom’s crackdown on Shiite protesters calling for greater rights.

The ruling by a special security tribunal sent a strong message that Bahrain’s Sunni monarchy is not easing off on punishments linked to the unrest despite appeals for talks with Shiite groups in the strategic Persian Gulf island nation, which is home to the U.S. Navy’s 5th Fleet.
