Syria accused of ‘punishing’ civilian areas

Tens of thousands of Syrians have been forced to flee their country by the security forces crackdown that has increasingly used heavy artillery to devastate opposition strongholds. 

Analysts say there is increasing evidence that the government of President Bashar al-Assad has been using “collective punishment” against civilians in its bid to crush the year-long protest movement.
