The Israeli army has used tear gas to break up a protest in the occupied West Bank where demonstrators threw rocks during a rally, demanding fairer treatment for Palestinian prisoners.
About 4.500 Palestinians are in Israeli prisons. Around 200 of them are being held indefinitely without charge.
One of them is Samer Issawi, who has been on hunger strike for more than 200 days. Two of his brothers are also detained, and the family say they are being targeted by the Israeli police.
