ISIS has executed 25 people in Mosul, northern Iraq, by lowering them in a vat of nitric acid, local news reports.
The more than two dozen men had been accused of spying on ISIS on behalf of Iraqi government security forces.
According to witnesses, the 25 alleged ‘spies’ had been tied together with a rope and lowered in a large basin containing nitric acid until their organs dissolved.
‘ISIS terrorist members executed 25 persons in Mosul on charges of spying and collaborating with Iraqi security forces,’ a source told Iraqi News in a statement.
‘ISIS members tied each person with a rope and lowered him in the tub, which contains nitric acid, till the victims organs dissolve.’
Nitric acid is a colourless, yellow or red, fuming liquid with an acrid, suffocating odour which is highly corrosive to all parts of the human body.
It is normally used in manufacturing ammonium nitrate for fertilizer and explosives, organic synthesis, photoengraving, etching steel, and reprocessing spent nuclear fuel.
The executions in Mosul follows a number of deadly bombings in the capital Baghdad, as ISIS hopes to rebound from a series of battlefield losses in Iraq.
