On Thursday the IDF told Physicians for Human Rights Israel (PHRI) that it had “no indication of the arrest or detention of the individual in question”.

The PHRI filed a petition with the Israeli High Court of Justice on Thursday, demanding Dr Abu Safiya’s location be disclosed. It said the court had given the IDF a week to comply.

Meanwhile Amnesty head Agnès Callamard said Israeli authorities must “urgently disclose his whereabouts”.

She said Israel had detained “hundreds of Palestinian healthcare workers from Gaza without charge or trial” and said they had been “subjected to torture and other ill-treatment and been held in incommunicado detention”.

Israel denies mistreating detainees.

Dr Abu Safiya’s family previously told BBC Arabic they believe he is being held at Sde Teiman military base in southern Israel, where Israeli forces have taken many detainees from Gaza for interrogation.

Whistleblowers have previously told the BBC and other international media of extremely harsh conditions for detainees there. Israel has said all detainees there are kept “carefully and appropriately”.

The IDF ordered everyone inside Kamal Adwan hospital to leave last Friday morning, giving the hospital about 15 minutes to move patients and staff into the courtyard, medical staff told the BBC.

Beit Lahia, where the hospital is located, has been under a tightening Israeli blockade imposed on parts of northern Gaza since October. The UN has said the area has been under “near-total siege” as the Israeli military heavily restricts access of aid deliveries to an area where an estimated 10,000 to 15,000 people remain.
