Outside Aleppo's ancient citadel, workmen are starting to mend the destruction of a war that has shattered the Syrian city's priceless historical heritage. The Aga Khan Development Network's cultural arm, which was behind a multi-million dollar restoration and urban development project around the Citadel, said it was also looking at possible rehabilitation of the area. Ali Esmaiel, head of the Aga Khan Cultural Service in Syria said the work to save Aleppo's heritage was difficult given the circumstances.
