Inside Mosul: Intimidation and punishment

Exclusive footage obtained by the BBC's Ghadi Sary from inside Mosul reveals how IS controls its population through intimidation and punishment.

The fall of Iraq's second-biggest city was part of the brutal, extremist group's rapid advance across the country, marking a huge setback for the Iraqi government and forcing thousands to flee.

Mosques and shrines have been blown up and local people have spoken about floggings and torture.
