The Islamic State has brutally executed over a dozen of its own fighters this week utilizing unprecedented, gruesome forms of torture to do so.

On Monday, seven ISIS militants were bound tightly by the hands and feet before being thrown into a giant cauldron of boiling water. According to MailOnline, the terrorists had fled an Iraqi battlefield in the heat of the conflict which took place in Sharqat in the Salahuddin province.

A truly horrific way to die, this is not the first time ISIS has used boiling water to torment others. A teenaged Yazidi girl who had been held prisoner by ISIS told MailOnline how her captors would often pour boiling water on her thigh if she refused to perform her ISIS rapists’ depraved sexual commands.

These seven were not the first to escape amidst an ongoing battle. Just last month, 19 ISIS soldiers fled amid battles against security forces in al-Shuhada and al-Nassaf in Central Fallujah, according to an unnamed informant who spoke with the American Herald Tribune. As punishment for their mutiny, the absconders were issued the death sentence by the ISIL court and were subjected to a firing squad, dying from bullets through the head.

Another six ISIS combatants were ruthlessly beheaded on Wednesday on charges of “treason”. Local sources told ARA News that the terrorist group had arrested six of its own security members of the al-Hisba department in the Iraqi city of Mosul on suspicion of passing information to the coalition.

“The ISIS leadership suspected that the al-Hisba members were leaking confidential information to the western coalition–whose airstrikes have recently killed top jihadi officials. After interrogation, the Mosul Sharia Court issued a decision to publicly execute the six suspects,” media activist Abdullah al-Malla told ARA News in Mosul, citing an ISIS official.

The six jihadists were then “beheaded in front of dozens of ISIS officials in central Mosul,” al-Malla divulged.

Wednesday’s beheadings came just a few days after the US-led coalition against the terrorist group carried out airstrikes on ISIS headquarters in northwestern Iraq, killing dozens of militants, including top Islamic State leaders.

“More than 30 ISIS jihadis were killed in the past two days, including top ISIS officials like Hamdouni and al-Bajjari,” local media activist Farad Mirani told ARA News.

The recent series of successful airstrikes against ISIS jihadis led the group to suspect that several of its own members had been secretly passing along confidential information regarding their leaders’ whereabouts.
