ALEPPO - Ruled successively by Hittites, Greeks, Romans and Ottomans, Aleppo's ancient city has survived violent change over thousands of years. But the modern weaponry of Syria's escalating civil war is proving too much.
The stone walls are pockmarked with bullet holes, whole houses have fallen after air strikes, and small wooden doors decorated with metal filigree are cracked from explosions.
For a month, rebels armed with assault rifles and grenades have battled President Bashar Assad's army along Aleppo's cobbled streets. Troops have used tanks, helicopters and jets to shoot, blast and bomb their positions.
