Witnesses reported a heavy security presence at main junctions in Manama from Sunday morning, especially at the Al-Farook interchange that was built on Pearl Square, which was razed a day after the protest was crushed.
Several checkpoints were set up and caused traffic jams, especially around the afternoon rush hour, they added.
