ISIS jihadis 'turned sinkhole off the Baghdad-Mosul highway into a mass grave for 4,000 bodies'
Four hundred meters deep and containing up to 4,000 bodies, this sinkhole is thought to be the biggest mass grave in Iraq.
The Khasfa sinkhole has swallowed the mutilated bodies of ISIS' enemies since the jihadis captured Mosul in 2014.
It is now so infamous that locals tremble when they speak of the atrocities committed there.

'Daesh would drive the victims to Khasfa in convoys of minibuses, trucks and pick ups,' a villager told The Telegraph.
'The men had their hands bound and their eyes blindfolded. They were taken to the sinkhole and shot in the back of the head.'
The local said he saw coachloads of blindfolded Yazidi men being pushed in alive and up to 2,000 policemen and soldiers shot there in one day
Human Rights Watch say:'Khasfa is definitely one of the biggest, if not the biggest, mass grave by Isil in Iraq.'
They estimate the hole was once 400 metrers deep before it was filled with around 4,000 bodies.
It is thought jihadis pushed in shipping containers and moved dirt over the hole with bulldozers to try to cover their crimes.

Meanwhile, at least 60 people were killed in IS attacks near a key northern Syrian town captured only a day earlier from the extremists by Turkish forces and their Syrian opposition allies.

Iraqi forces closely supported by the U.S.-led international coalition pushed into the first neighborhood of western Mosul and took full control of the city's international airport and a sprawling military base on the southwestern edge of the city, according to Iraqi officials.
The territorial gains were the most significant yet in the battle, now in its sixth day, to rout IS militants from the western half of Iraq's second-largest city.
