Beirut: Heavy clashes erupted between regime and rebel forces in Syria's divided city of Aleppo late Saturday after a unilateral ceasefire announced by government ally Russia expired, AFP reported.
Moscow had extended the unilateral "humanitarian pause" into a third day until 1600 GMT Saturday, but announced no further renewal of the truce despite a UN request for longer to evacuate wounded civilians.
The Syrian Observatory for Human Rights reported fierce fighting in several areas along the front line dividing the city, with three people wounded by shelling of the rebel-held Salaheddin and Al-Mashhad districts.
And the first air strikes since the end of the truce hit the opposition-controlled district of Sheikh Saeed where there was also heavy fighting, the monitor said.
AFP also reported sounds of fighting and artillery fire in the rebel-held eastern districts.
