An Israeli court gave sentences ranging from one to three years to seven Palestinian boys, aged between 14 and 17, for allegedly throwing stones at Israeli cars on Thursday, Palestinian prisoner rights group Addameer said in a statement posted on Facebook.
According to a Palestinian news agency, the boys were originally arrested in June 2015.
Addameer reported that at least 406 Palestinian children are now in Israeli prisons, with a quarter of them aged under 16 and most of the 700 children prosecuted annually are charged with throwing stones.
According to an annual UNICEF report titled "Children in Israeli Military Detention Observations and Recommendations," released in March 2015, the treatment of Israel towards Palestinian children is a "violation of international law."
The report and UNICEF's Working Group on Grave Violations against Children pointed out that children had often been subjected to multiple violations throughout the arrest, transfer, interrogation and detention phases.
The report found that 162 children were blindfolded during the transfer process from the place of arrest to the police station, 189 children were reported being painfully hand-tied, during arrests, 89 children were transferred on the floor of the vehicle from the place that they were arrested to the police station.
Israel passed new legislation on November 2015 which sentences Palestinian stone-throwers to minimum sentence of three years, parents of convicted could also face punishment.
According to the legislation, Palestinians charged with throwing stones at Israeli soldiers, civilians or vehicles will be given a three year minimum sentence and a maximum sentence of 15 years of imprisonment.
