Three months after a report condemned Bahrain's use of "excessive force" last year, the Gulf kingdom yesterday deployed armoured vehicles and unprecedented numbers of troops in an effort to prevent a repeat of the lethal clashes.
Heavy military reinforcements were sent to the mainly Shia villages outside the capital, Manama, to prevent people from gathering in response to a call by the main opposition movement al-Wefaq to mark yesterday's anniversary of the uprising against their Sunni rulers.
At the same time, the Government heralded a possible political crackdown on al-Wefaq by saying it would open legal procedures against the party, which it blamed for the violence that erupted after demonstrators sought to occupy Manama's heavily guarded Pearl Roundabout, the focal point of weeks of protests last year.
Armoured personnel carriers also patrolled the capital after pre-dawn skirmishes in which youths threw petrol bombs at police cars. Police responded by firing tear gas at about 24 protesters near Pearl Square. They detained 30 people, with six United States citizens reported to be among those arrested.
Yesterday, Bahrain's information affairs authority said the six US citizens had been deported "for applying for tourist visas under false pretences".
