Medical workers in Israel have told the BBC that Palestinian detainees from Gaza are routinely kept shackled to hospital beds, blindfolded, sometimes naked, and forced to wear nappies – a practice one medic said amounted to “torture”.

A whistle-blower detailed how procedures in one military hospital were “routinely” carried out without painkillers, causing “an unacceptable amount of pain” to detainees.

Another whistle-blower said painkillers were used “selectively” and “in a very limited way” during an invasive medical procedure on a Gazan detainee in a public hospital.

He also said critically ill patients being held in makeshift military facilities were being denied proper treatment because of a reluctance by public hospitals to transfer and treat them.

One detainee, taken from Gaza for questioning by the Israeli army and later released, told the BBC his leg had to be amputated because he was denied treatment for an infected wound.
