A Palestinian prisoner has died in Israeli custody despite longstanding calls to release him and claims of Israeli medical negligence following his late diagnosis with cancer more than a year ago.

Palestinian authorities said that 50-year-old Nasser Abu Hmaid died on Tuesday morning at the Assaf Harofeh Israeli hospital near Tel Aviv.

He was transferred in a sudden manner on Monday afternoon from the Ramla prison clinic to the hospital after his health seriously deteriorated and he slipped into a coma.

A general strike started on Tuesday morning with stores, schools and businesses shut across the occupied West Bank to mourn Abu Hmaid’s death, including Ramallah, Hebron, Nablus and Jenin.

Palestinian Authority President Mahmoud Abbas said in a statement that Abu Hmaid was “martyred as a result of the policy of deliberate medical negligence” and held the Israeli occupation responsible.

Abu Hmaid was diagnosed with an advanced stage of lung cancer in August 2021 after Israeli authorities delayed the provision of medical examinations and treatment

His family, prisoner groups and officials had since then launched a campaign calling on Israel to release him and warned that he was being exposed to “a slow death” through medical negligence.
