ISIL Takfiri militants have kidnapped 1,500 Ezadi children since taking over Iraq's Northern city of Sinjar, the Iraqi Observatory for Human Rights said in a recent report.
The abducted children, between 12 and 16 years old, are being taught radical ideas and are receiving military training, the observatory added, World Bulletin reported.
"ISIL militants may succeed in convincing the seized children to disbelieve in their religion and kill their own people in the future," Mahd Karim, a member of the observatory said.
The organization called on Iraq's government and the UN to free the youth before they turn into ISIL terrorists.
ISIL controls most of Sinjar, 77 miles West of Mosul, which is home to many Ezadi Kurds.
The Ezadi population is estimated at 600,000 and a number of Ezadi minority groups live in Turkey, Syria, Georgia and Armenia.
Meanwhile, ongoing battles between ISIL and Iraqi security forces left 51 militants dead in Anbar and Salahuddin, the Iraqi Ministry of Defense said Tuesday.
The ISIL Takfiri terrorists currently control parts of Syria and Iraq. They have threatened all communities, including Shiites, Sunnis, Kurds, Christians, Ezadi Kurds and others, as they continue their atrocities in Iraq.
Senior Iraqi officials have blamed Saudi Arabia, Qatar, and some Persian Gulf Arab states for the growing terrorism in their country.
The ISIL has links with Saudi intelligence and is believed to be indirectly supported by the Israeli regime.
