At least 100 Palestinian prisoners were injured on Monday during clashes with the guards in the Israeli Ofer Prison in the West Bank, according to the Palestinian Prisoners Club Association.

The association, which is a Palestinian non-governmental organization, said in a press statement that the prisoners were injured as a result of the successive repression and assaults of the Israeli services against the prisoners on Monday.

According to the statement, the Israeli guards of the prison used rubber-coated metal gunshots, tear gas canisters, percussion bombs, clubs and dogs.

"Most of the prisoners were injured by rubber-coated metal gunshots and many of them were referred to Israeli hospitals," said the statement, adding that most of them were brought back to the prison and 20 remained for treatment.

The association warned that "such an aggressive assault on the prisoners is brutal and hasn't happened in ten years."

The statement called on the international organizations to immediately intervene to put an end to the brutal and aggressive escalation against the prisoners.

Israel Radio reported that a number of Palestinian prisoners violated the prison's discipline and set fire on the prison's rooms after the prison's administration punished 12 prisoners for hiding smuggled cellular phones.

An official Palestinian figure said that Ofer Prison has around 1,200 Palestinian prisoners out of 6,000 Palestinians imprisoned in Israeli prisons, jails and detention camps.
