1840 GMT: An EA correspondent reports on a security crackdown tonight in Bahrain:
All Sitra entrances and exists are blocked by checkpoints, not allowing anyone out or in unless they been searched. The whole village is filled with police forces, some in their jeeps while others on foot. They blocked the road near the police station too, not allowing anyone to pass there.
I believe there will be houses raids, as in Bani Jamra a couple days ago.
