In Syria's second city of Aleppo, hundreds are said to be fleeing their homes

There have been heavy clashes between security forces and rebels in Syria's second city of Aleppo, activists say.

The fighting was centred on the Salah al-Din district, but had also spread to Sakhur and Haydariya, the Syrian Observatory for Human Rights reported.

Aleppo has so far been spared the daily bloodshed seen in other cities since the uprising began in March 2011.

The violence came a day after the UN Security Council voted to extend the UN observer mission for a "final" 30 days.
