27-year-old Palestinian detainee Ammar Ibrahim al-Hamour from Jenin province has been on an open ended hunger strike for 13 days running in protest at being held in Israeli jails without trial.
A letter written by Palestinian detainees at Negev jail sounded distress signals over the exacerbated health status of prisoner al-Hamour.
The letter called for an urgent intervention to save al-Hamour before it is too late after his health has taken a turn for the worse.
Al-Hamour has been diagnosed with hypertension and has refused to take in drugs in jail in response to his renewed administrative term with neither charge nor trial.
Al-Hamour was arrested by the Israeli occupation forces last February and was held in administrative detention without trial.
In August the occupation authorities extended his administrative prison-term which made him declare his hunger strike 13 days ago.
