BEIRUT — Activists say Syrian troops have shelled two rebel-held neighborhoods in the central city of Homs.
The Britain-based Syrian Observatory for Human Rights says Saturday's bombardment lasted for about an hour. It says there were no reports of casualties.
The shelling comes two days after a cease-fire brokered by international envoy Kofi Annan went into effect.
Violence reported over the last two days is much less than the daily norm of clashes and shellings before the truce.
Activist Tarek Badrakhan, who is based in Homs, and the Observatory said the shelling targeted the neighborhoods of Jouret el-Shayah and Qarabees.
The truce is at the center of Annan's six-point plan to stop the bloodshed and launch talks between the regime and the opposition.
