The Palestinian Prisoners Club said Friday that four Palestinian prisoners in "Nafha" prison are continuing their open hunger strike for the sixth day in a row, in protest of their administrative detention by the Israeli occupation.

"The Nafha prison administration transferred them to the cells after they announced the strike on July 30," the club indicated in a statement.

The club mentioned that the prisoners on hunger strike are Sayf Hamdan (29 years old) from Nablus, Saleh Rabiaa (22 years old) from Jenin, Qusay Khader (25 years old) from Al-Amari camp in Ramallah, and Osama Khalil (23 years old) from Al-Faraa camp.

The number of Palestinian administrative prisoners exceeded 1,200, the highest since 2002, the club highlighted.

Palestinian statistics indicate that the number of Palestinian prisoners in Israeli occupation prisons reached about 5,000 in 2023, including 160 children and 32 women.

It is worth noting that administrative detention is an arbitrary policy used by the Israeli occupation against Palestinians, where prisoners are held in Israeli prisons without charges filed against them, and their detention is renewed as a precautionary measure.

There is usually no evidence to incriminate the prisoners in any case, nor are any cases brought before their lawyers. The arrests are approved by military judges who receive an order signed by a commander of the occupation military in the occupied West Bank, along with secret intelligence materials about each prisoner.

A report shows that there are currently 400 Palestinian prisoners who have spent more than 20 consecutive years in Israeli occupation prisons, while there are dozens of others who were rearrested and spent more than 20 years in two terms.

According to the report, 554 Palestinian prisoners are sentenced to life imprisonment, and 23 are serving long-term sentences and were arrested by Israeli occupation forces before the signing of the 1993 Oslo Accords.

The Palestinian rights groups mentioned that the Israeli occupation prison administration subjects Palestinian prisoners to systematic torture, harassment, and repression.
