The court ruled that he should be executed and the sentence was carried out in front of a crowd of 2000 people in the Sukkari district on September 5th, followed by celebrations among the local citizens.
The above is based on the statement provided by the brigade, so it's not possible to independently confirm the details, nor confirm the individual executed was guilty of the crimes he was accused of and confessed to, nor is it possible to confirm the events surrounding his confession and execution.
