RAMALLAH (Ma'an) -- The PA ministry of prisoners said Wednesday that Palestinian detainees on hunger-strike in Israeli jails have set Monday as the deadline for an Israeli response to their demands.

After Monday, prisoners will decided their next steps based on the Israeli prison administration's response, the ministry said.

Last Tuesday, marking Palestinian Prisoners Day, at least 1,200 prisoners in Israeli jails launched an open-ended hunger strike. They are demanding a change in their living conditions, and an end to solitary confinement, night raids and bans on family visits for prisoners from Gaza.

Prison authorities have responded by denying them family visits and separating them from inmates not taking part in the protest.

More than 4,000 Palestinians are imprisoned in Israel, around 320 of them without any charge.
