Hundreds of shops in Aleppo's ancient market were set on fire during fighting between government soldiers and rebels yesterday.
Activists say the army shelled the market and then prevented people from entering the area to put the flames out. So far almost 1000 shops are thought to be destroyed.
Aleppo's Old City is one of several locations in Syria declared world heritage sites by UNESCO, the United Nations cultural agency, that are now at risk from the fighting. The eighteen month conflict has killed an estimated 30,000 people.
