“It would be better to drown these prisoners, in the Dead Sea if possible, since that’s the lowest point in the world.”-Israeli Deputy Prime Minister Avigdor Lieberman
Since the beginning of the second Intifada in September 2000, over 4,000 Palestinian children have been arrested. 
A few of them can be viewed in a short excerpt from British ITV's expose of Palestinian children prisoners:
"According to the Convention on the Rights of the Child, adopted on 20 November 1989 and entered into force on 2 September 1990 (to which Israel is a signatory), and to relevant Israeli law, a child is defined as every human being under the age of 18 years." 
Palestinian children in prison are mistreated as badly as adults under Israeli military regulations in the Occupied Palestinian Territories. Palestinian children over twelve "may be charged and sentenced in military courts. Between the ages of 12-14, children can be sentenced for up to 6 months for minor offences, including throwing a stone. After the age of 14, Palestinian children are tried as adults, in violation of international law. There are no juvenile courts for Palestinian children. They also frequently serve their sentences in cells with adult prisoners, which is in violation of international law." 
"Palestinian children arrested from Israeli military checkpoints are often made to wait for hours at the checkpoint, with their hands cuffed, before they are transferred to detention and interrogation centers. More often than not, Palestinian child detainees are subject to beatings, curses and threats during the transfer. In most cases, their families are not informed of their arrest, with child prisoners additionally being transferred from one prison to another without informing the family. As a result, it often takes some time before a child detainee is located and the family informed of his/her location." 
Arrests are frequently made in raids in 'Holy' Land refugee camps in the middle of the night.
