A firefight erupted on Thursday between Syrian government forces and opposition fighters in Aleppo a few hours after the start of a one-sided truce sponsored by Russia, the UK-based Syrian Observatory for Human Rights reported.

The clashes broke out after some terrorist groups targeted the Bostan al Qasr crossing using mortar shells and machine guns, Sky News TV channel reported.

A planned three-day humanitarian pause came into effect in Aleppo at 05:00 GMT Thursday to let civilians leave the city along six corridors, in addition to two corridors opened for militants.
