Syria army 'to observe ceasefire' over Eid al-Adha

Syria's military says it will adhere to a four-day ceasefire to begin on Friday for the Muslim holiday of Eid al-Adha.

The truce will begin at 0600 (0400GMT), reported Syrian TV, adding the army would retaliate against rebel attacks.

The truce was proposed by UN and Arab League envoy Lakhdar Brahimi, who hopes it will lead to a peace process.

The news came as rebels said they had advanced into several central areas in Aleppo, Syria's largest city and a key battleground in recent months.
