Forces cordon off protest site
Witnesses said security forces in Bahrain's capital are blocking roads around a former protest hub after clashes with anti-government demonstrators in the Gulf island kingdom.
Witnesses said tanks and police vehicles surrounded Pearl Square, which had been the centrepiece for Shiite-led protests calling for greater rights from Sunni rulers in the strategic nation, which is home to the US Navy's Fifth Fleet.
The witnesses spoke on a condition of anonymity because they fear reprisals.
The blockades came after protesters in a Manama neighbourhood called for a march back to Pearl Square, which was stormed by security forces several weeks after pro-reform demonstrations began in February.
Major protests have been crushed, but small-scale clashes have occurred nearly nightly for weeks.
