Former patients told ITV News Tishreen Hospital in Damascus has become a 'slaughterhouse' where opponents of the regime are sent to die.

As President Bashar al-Assad prepares to return to the world stage, ITV News learns of a new mass burial site used by his regime.

The invitation marks a shift in international relations towards al-Assad, who has been frozen out of much regional politics in recent years.
