A wave of protest is spreading in North Africa and the Middle East.
In Bahrain, following the violent removal of anti-government demonstrators, protests have been banned and the military has been ordered to tighten its grip, state TV reports.
The interior ministry said the army will take every measure necessary in order to preserve security and warned people to stay off the streets.
In the centre of the country’s capital Manama, riot police attacked a makeshift encampment of pro-reform protesters, killing at least three and injuring many others.
Following those events, Manama was rocked by sporadic clashes.
An announcement was made on state television, saying that the army had taken control of “key parts” of Manama.
In effect tanks, army patrols and military checkpoints on key streets, along with helicopters deployed overhead, are shutting the capital down.
Roads leading Pearl Square, the main protest area, have been closed with barbed wire.
A ministry spokesman said: “The security forces have stressed that they will take every strict measure and deterrent necessary to preserve security and general order.”
