The Syrian regime is reported to have deployed its security forces around a number of urban centers in advance of potential further anti-regime demonstrations after Friday prayers.
Reports quote witnesses as saying military units have been deploying around the Mediterranean coastal town of Banias, a site of previous unrest, and elsewhere.
In another development, activists say security forces have detained more than 200 people in the Damascus suburb of Saqba.
Elsewhere, the Syrian army said May 5 that it had begun withdrawing forces from Deraa, the southern city where the Syrian uprising began.
But residents say tanks and troops remain around the city.
Human rights groups say more than 550 civilians have been killed by security forces and thousands of people injured or arrested during the past seven weeks of demonstrations against President Bashar al-Assad's regime.
The regime has blamed "armed terrorist groups" for instigating the unrest and killing civilians and members of the security forces.
