These measures may escalate to a full-blown hunger strike in order to demand improvements to living conditions for prisoners and halting "arbitrary and repressive acts against them,"  the authority said in a statement.

Prisoners are demanding an end to solitary confinement, administrative detention and "collective punishment."

They are also calling for better medical care and halting security raids on their cells, arbitrary searches and transfers, the release said.

The inmates have given the prison authorities a chance to reconsider its position on their demands. "If their demands are not met, they will begin a series of escalatory steps as the situation has become untenable," the authority added.

Over 7,000 Palestinians are currently languishing in Israeli prisons, according to official Palestinian figures.
