Youths bring parkour to Syria's war-battered east Aleppo

Omar Kosha and his team of six have for years used the streets, gyms and public gardens of the western sector of the Syrian city of Aleppo to practise parkour ... now they have a whole new terrain for their extreme sport. The thrill-seeking youths spin in the air, flipping across the roofs of semi-destroyed buildings with flimsy and crumbling structures.
With quick and agile movements, they bound up walls and through windows, before leaping across terrifying gaps or several floors down onto piles of debris.
