A total of 291 Palestinians are currently in Israeli prisons, a Palestine Liberation Organization (PLO) official said on Sunday.
In a statement, Hanan Ashrawi, a PLO Executive Committee member, said: "There are currently nearly 5,900 Palestinian prisoners, including 291 children in Israeli prisons."
The statement comes after teenaged Palestinian resistance icon Ahed al-Tamimi and her mother were released by Israeli authorities after an eight-month-long detention.
"Israel persistently violates the rights of Palestinian political prisoners while the international community turns a blind eye to such illegal behaviour and inhumane treatment," said Ashrawi.
Al-Tamimi became an international icon for Palestinian resistance after she was filmed slapping an Israeli soldier during a raid on her home to arrest her brother.
Israeli forces arrested the Palestinian girl in December 2017 after a viral video showed her slapping an Israeli soldier; later an Israeli court handed down an eight-month-long sentence in March for her "attack" on an Israeli soldier.
In 2012, Istanbul's Basaksehir Municipality had granted al-Tamimi the prestigious Hanzala Courage Award for defying Israeli soldiers after she was photographed showing her fists to the occupying forces.
