The Arabic-language al-Sumaria news website quoted an informed source as saying that the terrorists killed the people for cooperating with and spying for the Iraqi security forces.
The source, who spoke on condition of anonymity, said Daesh (ISIS / ISIL) terrorists tied the people with rope and put them in a large basin containing nitric acid.
The source further added that the execution was performed in public to scare other people.
On May 13, ISIS terrorists also executed 11 residents of Mosul on charges of using mobile phones.
ISIS terrorists burned the entire five members of an Iraqi family alive in Kirkuk city on May 10 after accusing them of trying to escape terrorist-held territories.
In late April, ISIS members alsoexecuted 250 women in Mosul after the victims did not accept a proposal to temporarily marry the militants.
Earlier this month, United Nations Special Representative for Iraq and Head of the United Nations Assistance Mission for Iraq (UNAMI) Jan Kubis told the UN Security Council that over the recent months, more than 50 mass graves have been found in various parts of Iraq that were previously controlled by ISIS.
Gruesome violence has plagued the northern and western parts of Iraq ever since ISIS terrorists launched an offensive in June 2014 and took control of portions of Iraqi territory.
The militants have been committing heinous crimes against all ethnic and religious communities in Iraq, including Shias, Sunnis, Kurds, Christians and others.

Civilians in Mosul are encouraged to execute hostages from the Iraqi security forces, according to Ara News:
“Islamic State’s jihadis brought five hostages from the Iraqi security forces to the Bab al-Toub square in central Mosul to execute them in public on Thursday,” media activist Abdulla al-Malla told ARA News in Mosul.
“The group then asked for volunteers from the audience to participate in the execution of the hostages, who were described by ISIS as ‘apostates’ and ‘enemies of the Caliphate’,” the source continued. “When nobody volunteered to help the militants in the execution, the group chose five men from the public and forced them to shoot the hostages in the head.”
Speaking to ARA News, head of the Nineveh media center Raafat al-Zarari said that ISIS is trying to involve innocent civilians in its brutal acts in order to support its propaganda.
“By showing civilians as partners in executing what the group considers as apostates and enemies, ISIS is actually trying to show that it still has a social incubator in Mosul and that people are supporting the group’s alleged Caliphate,” Zarari said.
More than one million and a half of civilians are still stranded in the ISIS-held city of Mosul in Iraq’s northwestern Nineveh province, according to local activists.
