Beirut: Activists say Syrian troops have shelled two rebel-held neighbourhoods 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 ceasefire 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 shelling before the truce.
Activist Tarek Badrakhan, who is based in Homs, and the Observatory said the shelling targeted the neighbourhoods of Jouret el-Shayah and Qarabees.
The truce is at the centre of Annan`s six-point plan to stop the bloodshed and launch talks between the regime and the opposition.
