Al-Jazeera Video: Young men take up arms in Syria's west

"Syrian President Bashar al Assad has sharply criticised foreign powers who have raised the possibility of outside intervention.

He has lost control of large parts in the country's west where teenage fighters have taken up arms against him.

The young men soldier on, defending their communities against tanks and fighter jets, in spite of a lack of sophisticated weaponry.
