The PPCS’ spokesman Riyadh Al-Ashqar said that the number included 294 renewed orders and 138 new orders.
He added that the orders ranged from two to six months.
Al-Ashqar said that the continuous Israeli detention of Palestinian prisoners without trials is a clear violation of international laws and conventions.
He said that there are currently 500 Palestinian prisoners being held under administrative detention inside Israeli jails, including four MPs, two children and one woman, the Middle East Monitor reported.
Six have launched a hunger strike in protest of their continued detention.
Al-Ashqar called for the international community to put an end to Israel’s disregard for international laws and conventions.
He also called for the Palestinian Authority to urgently raise the issue of administrative detention inside the Israeli jails to the ICC.
There are 5,700 Palestinian prisoners inside Israeli jails, including 48 women, 230 children, and 700 who require medical care.
