RAMALLAH (Ma’an) -- Palestinians in Israel's Hadarim jail will launch a partial food strike to support prisoners on long-term hunger strike, a lawyer said on Sunday.

The prisoners will return their meals one day each week, the Palestinian prisoners society lawyer said.

Prisoners say that a deal to end mass hunger strikes agreed with prison authorities in May has not been implemented, noting that at least two prisoners are still held in solitary confinement, which the agreement was meant to end.

Palestinian prisoners launched a one-day hunger strike on Tuesday in solidarity with four prisoners currently undertaking prolonged strike action, Qaddura Fares, head of the Palestinian Prisoners Society, told Ma'an.
