Paris: Six historical sites in Syria including mosques, citadels and souks are in peril because of the country`s civil war, the UN cultural agency has said.
Unesco said in a statement that the sites are "of outstanding universal value for humanity as a whole" and urged international support to safeguard them.
The historical centres in Damascus, Bosra and Aleppo, as well as the desert oasis of Palmyra, a cultural centre of the ancient world, were added to Unesco`s list of World Heritage sites.
Aleppo`s old city, in particular, has "witnessed some of the conflict`s most brutal destruction," Unesco said, adding that the old citadel was "caught in the line of fire".
The security situation has left Syria`s archaeological sites susceptible to damage. Illicit trade in Syria`s rich archaeological heritage has flourished during the two-year war between rebels and forces loyal to President Bashar al-Assad.
