Syrian government forces have regained control of areas they lost over the past two weeks to a rebel offensive on the edge of the northern city of Aleppo.

The Britain-based Syrian Observatory for Human Rights said Saturday that government forces and their allies have regained control of Al-Assad and Minyan districts, west of Syria's largest city.

Syrian state media reported that the two districts have been retaken.

The Observatory said the fighting left 508 dead, including civilians and fighters from both sides.

The insurgents seized a couple of strategic areas in western Aleppo in an offensive launched on Oct. 28. They had hoped to break a monthslong siege on rebel-held eastern Aleppo.
