A mass hunger strike across Israeli prisons continued on July 23 in protest of Israel's detention of Palestinians without charge or trial. At least 48 Palestinian prisoners now participating in the open hunger strike in support of hunger-striking prisoners Bilal Kayid and brothers Muhammad and Mahmud al-Balboul, according to a statement released by the Palestinian Committee of Prisoners' Affairs. The committee said in a statement that solidarity hunger strikes are continuing to put pressure on the Israeli prison administration and government to comply with the demands of the striking prisoners and to end Israel’s controversial policy of administrative detention—internment without charge or trial based on undisclosed evidence almost exclusively used against Palestinian detainees.

Head of the committee Issa Qaraqe called for a wide-scale action in all Palestinian cities to support the hunger-strikers in the statement. Qaraqe stressed that administrative detention violates international laws and humanitarian conventions.

Kayid, a member of the Popular Front for the Liberation of Palestine (PFLP), Palestine's most popular left-wing political faction, has been on hunger strike for 40 days in protest of being placed in administrative detention by Israel on the day he was scheduled to be released after completing a 14-and-a-half-year prison sentence. Kayid is currently being treated at Israel's Barzilai Medical Center in Ashkelon, reportedly in serious condition after his health severely deteriorated last week.

Kayid, a resident of the town of Asira al-Shamaliya in the northern occupied West Bank district of Nablus, was originally detained in 2002 for alleged involvement in the Abu Ali Mustafa Brigades, the armed wing of the PFLP.

Hundreds of PFLP-affiliated prisoners have staged several solidarity mass hunger strikes to demand Kayid's release, while 33 prisoners announced an open hunger strike in solidarity with Kayid on July 18, and more than a dozen joined over the following days. The latest mass hunger strike was declared alongside an announcement by Palestinian factions that protests would continue to escalate in the coming weeks to demand Kayid's release.

Meanwhile, brothers Muhammad and Mahmoud al-Balboul, held in Israel's Ofer prison, declared an open hunger strike earlier this month, and have been on strike for 20 days. The brothers were detained on June 9 in Bethlehem, just two months after their 14-year-old sister, Nuran, was detained after attempting to cross Israel's 300 checkpoint between northern Bethlehem and Jerusalem for allegedly possessing a knife, an accusation that locals denied.
