An Israeli prison guard deployed to watch a hospitalized Palestinian prisoner reportedly fired tear gas into the intensive care unit room where the man was convalescing after treatment for injuries sustained during interrogation.

The Hebrew newspaper Maariv reported that an Israel Prison Service guard “accidentally” emitted tear gas in Samer Arbeed’s room at the Hadassah hospital in Jerusalem earlier this month, requiring doctors to intervene.

Maariv said the incident was never reported to the prison service.

Arbeed was hospitalized on 27 September following his interrogation by Israel’s domestic intelligence agency, the Shin Bet.

But being hospitalized has not stopped his ordeal and Israeli prison authorities have continued to question Arbeed even while in the ICU.
