RNA - The Israel Prison Service had rejected many Palestinian calls for the release of al-Sayeh, who was suffering from bone and blood cancer, despite his deteriorated health condition, Palinfo reported.
Al-Sayeh, a resident of the West Bank city of Nablus, was arrested by Israeli occupation forces in October 2015.
In mid-July, Nassar Taqatqa, 31, died in solitary confinement in the Israeli prison of Nitzan amid reports that the inmates are subjected to medical negligence and torture in the regime’s jails.
The prisoners and ex-prisoner affairs committee held the Israeli authorities fully responsible for his death.
Some 7,000 Palestinians are currently behind bars in 17 Israeli prisons and detention centers, according to reports.
More than 400 Palestinians are being held without trial under so-called administrative detention, which is a policy according to which Palestinian inmates are kept in Israeli detention facilities without trial or charge. Some Palestinian prisoners have been held in administrative detention for up to 11 years.
