Elyas Abu Safia says his father can barely breathe or speak after more than 555 days in Israeli prison.

The son of a prominent Palestinian doctor abducted and held by Israel without charge has issued an urgent appeal for his father’s release, warning that his health has sharply deteriorated after more than 555 days in prison, as a rights group warned that his life was in danger.

Elyas Abu Safia, the son of Dr Hussam Abu Safia, said in a video message on Sunday that his father, the director of Kamal Adwan Hospital in northern Gaza, showed signs of severe abuse after Israeli authorities transferred him to solitary confinement in a maximum-security prison.

“The day before yesterday, the lawyer Nasser Odeh managed to visit my father, where he told us painful details about this visit,” said Elyas, who is also a doctor.

“My father was unable to breathe. My father was unable to speak,” he said, adding: “His face was disfigured from the marks of torture and pain, and the blood he endured inside the prison, especially after the last court session held in Jerusalem.”

Israeli forces arrested Abu Safia at work on December 27, 2024, as they intensified their attacks on northern Gaza’s healthcare system as part of the genocidal war against Palestinians in Gaza. Two months earlier, an Israeli drone attack killed another of his sons, Ibrahim, at the entrance of the hospital where he worked.

Elyas accused Arab and Muslim leaders of abandoning his father.

“You deprived us even of your voices, your solidarity and your support, which should have been there from the start of the detention,” he said.

“But sadly, your silence is a betrayal and a crime, and complicity in torturing my father and the hostages inside Israeli prisons,” he added.

‘The most shocking testimony’

Physicians for Human Rights Israel warned that Abu Safiya’s life is in immediate danger after his transfer to the Rakefet section of Nitzan prison.

The group said lawyer Nasser Odeh visited Abu Safia on July 2 and documented severe injuries, signs of assault, difficulty breathing and repeated loss of consciousness. It said guards brought him into the visit with his hands and feet bound and surrounded him with masked officers.

Odeh also saw fresh bruises and injuries on Abu Safiya’s head, around his eyes, ears and neck. The wounds were so severe that the lawyer struggled to recognise him, the group said.

“The information we received raises serious and immediate concerns for Abu Safiya’s life. The lawyer’s testimony is among the most shocking we have heard since the beginning of the war: a man detained without charge tells his lawyer that he believes they will kill him, after he arrived for the visit injured, suffering from difficulty breathing, and on the verge of losing consciousness,” Naji Abbas, director of the Prisoners and Detainees Department at Physicians for Human Rights, told the official Palestinian news agency Wafa.

Israeli authorities have not filed charges against Abu Safia. They classified him as an “unlawful combatant”, a designation Israel has used to hold Palestinians for prolonged periods without trial.

Physicians for Human Rights has demanded his release, along with other imprisoned Palestinian doctors. In March, United Nations experts also called on Israel to free Abu Safia immediately and ensure he receives medical care.

He is one of 14 Palestinian doctors from Gaza currently held by Israel without charge.
