Sheikh Anwar Assi al-Obeidi said on Wednesday that 118 men and nine boys were originally captured three days ago from Rubaidha village, east of Tikrit, but that 21 men have since been released.
The boys, aged nine and 10, are still being held along with the remaining men at an unknown location, Sheikh Anwar said.
He said that most of those captured have relatives fighting against ISIS and that 600 members of the al-Obeid tribe, where he is the paramount sheikh, have been killed by ISIS fighters since June.
"ISIS have taken our men in retaliation for their support to the security forces and being part of the Sunni tribes that oppose ISIS’s ideology," the sheik said. "This is an attempt by ISIS to mount pressure on their relatives and family members whom have took up arms against ISIS."
He said news of the kidnapping had not been reported earlier because phone services had been cut off in the area. The news came a day after ISIS fighters reportedly captured at least 70 Assyrian Christians in Hassakeh province in northeast Syria. A new UN report released this week documented widespread human rights violations committed by ISIS in Iraq between September and December last year.
“Members of Iraq’s diverse ethnic and religious communities, including Turkmen, Shabaks, Christians, Yezidi, Sabaeans, Kaka’e, Faili Kurds, Arab Shia, and others have been intentionally and systematically targeted by ISIS and associated armed groups and subjected to gross human rights abuses," the report said.
Meanwhile on Wednesday, Iraqi security forces evacuated 300 families from the town of al-Baghdadi.
