BEIRUT -- Activists say Syrian forces are shelling opposition strongholds as thousands gather across the country in weekly anti-government protests.
There was no immediate word on casualties.
Friday's violence was reported by the Britain-based Syrian Observatory for Human Rights, which has a network of activists on the ground, and by the opposition Local Coordination Committees.
The groups said government forces shelled the Qusour and Jobar neighborhoods in Homs province. Also Friday, there were protests in Damascus, Aleppo and the southern Daraa province.
More than 250 U.N. observers have fanned out around Syria to monitor a peace plan brokered by Kofi Annan, but the cease-fire is violated every day by both sides.
