Syrian media said government troops had "captured and cleared" the neighbourhood of Midan in Aleppo today.
The state-owned Sana news agency said soldiers had killed "dozens" of rebels across the city. Opposition fighters say over 50 people had been killed the previous day in Aleppo and in the outskirts of Damascus.
Despite government advances hope for an early end to the country's civil war - which has cost over 20,000 lives since an uprising against President Bashar al-Assad began last year - were thin.
The new "international envoy" Lakhdar Brahim, who is tasked with bringing the government and rebels to the negotiating table, said after three days of talks with both on Saturday: "I repeat - I have no plan," though he did express hope that "such a plan will emerge."
