Al-Jazeera Video: Syrian defectors 'buying weapons from army'

"Al Jazeera has gained exclusive footage from inside Syria of the army defectors fighting to topple President Bashar al-Assad's government.

The Free Syrian Army is claiming that a steadily increasing number of defected soldiers are joining its ranks.

The group is believed to number anywhere between 1,000 and 25,000 troops, divided over 22 battalions spread across the country.

The soldiers say their former comrades are selling them weapons.
