Where does ISIL keep all the dead bodies after executions

A new video has emerged over the internet showing militants from the so-called Islamic State of Iraq and Levant (ISIL) dumping bodies of their victims in a valley in their main stronghold in Syria’s Raqqa.
Syria’s Raqqa has been suffering under ISIL rule for months, with the group imposing its own law marked with severe punishments and heartless executions.
While there are many reports over people going missing after getting arrested by ISIL militants, locals say that many of them never saw bodies of their relatives after they got executed by ISIL.
The new video shows a number of ISIL militants throwing the dead in a big hole among the hills surrounding Raqqa, called al-Houte.
The video starts with public execution of three people, with their heads covered in black bags.
The militants take the victims’ lives by shooting in their heads at close range and transfer the bodies to al-Houte.
All bodies are thrown in a big hole among the hills.
The ISIL radical group is one of the main terrorist groups which entered the war in Syria to join foreign-backed militants to topple the government.
The group now calls itself simply the Islamic State, after announcing to form a caliphate in parts of Iraq and Syria.
ISIL is known for its extremist acts of violence and atrocities against civilians and Syrian and Iraqi army soldiers.
