Palestinian children detained by Israeli authorities face systematic abuse that violates international law, the United Nations Children Fund (UNICEF) has said in a report.

UNICEF estimated that 700 Palestinian children aged between 12 and 17 were arrested by Israeli security forces every year in the occupied West Bank. The world organisation said it had identified some examples of practices that "amount to cruel, inhuman or degrading treatment or punishment according to the Convention on the Rights of the Child and the Convention against Torture".

According to the report, which was released on Wednesday, most of the youths are taken into custody for throwing stones at Israeli security forces. Tel Aviv says it takes such incidents seriously, noting that rock-throwing has caused Israeli deaths.

Ill-treatment of Palestinian minors typically begins with the arrest itself, often carried out in the middle of the night by heavily armed soldiers, and continues all the way through prosecution and sentencing, according to the report.
