Another is said to have received the same horrific treatment in the nearby town of Bukamal, according to Justice for Life Observatory.

Prior to this, all three were said to have been kept in cages for hours on end like animals and lashed 70 times.

Rami Abdelrahman, from the UK-based Syrian Observatory for Human Rights, said they were held up on the crosses as 'example', Daily Mail reports.

'We heard of similar instances happening in Raqqa two days ago,' he said

During Ramadan last year, ISIS (Islamic State , ISIL , IS and Daesh) ruthlessly caged and crucified 94 people, including five children, after they were caught breaking their fast.
