Health officials in Gaza say many of the 90 returned bodies bore marks of violence and possible executions.

Gaza’s Ministry of Health says it has received the remains of 45 Palestinians who were held in Israeli custody via the International Committee of the Red Cross, bringing the total number of bodies returned to 90 as part of a United States-brokered ceasefire deal.

Medical teams are continuing to examine, document and prepare the bodies for delivery to families “in line with approved medical procedures and protocols”, the Health Ministry said in a statement on Wednesday.

Under a ceasefire deal backed by US President Donald Trump and aimed at ending the two-year Gaza war, Israel was to turn over the bodies of 15 Palestinians for every deceased Israeli returned. The remains of 45 people were returned on Monday.

Palestinians awaited information about the bodies that arrived at Nasser Hospital on Tuesday and Wednesday. The forensics team described disturbing conditions, bearing signs of physical abuse.

Some of the Palestinian bodies were blindfolded and handcuffed, indicating “field executions” may have taken place, medical sources told Al Jazeera.

Israel is expected to hand over more bodies, though officials have not said how many are in its custody or how many will be returned. It remains unclear whether the bodies were dug up from cemeteries by the Israeli army during its ground offensive or if they belong to detainees who were killed during the Israeli assault. Throughout the war, Israel’s military has exhumed bodies as part of its search for the remains of captives.

As forensic teams examined the first remains returned, the Health Ministry on Wednesday released images of 32 unidentified bodies to help families recognise missing relatives.

Many appeared decomposed or burned. Some were missing limbs or teeth, while others were coated in sand and dust. Health officials have said Israeli restrictions on allowing DNA testing equipment into Gaza have often forced morgues to rely on physical features and clothing for identification.

The forensics team that received the bodies said some arrived still shackled or bearing signs of physical abuse.

“There are signs of torture and executions,” Sameh Hamad, a member of a commission tasked with receiving the bodies at Nasser Hospital, said.

The bodies belonged to men aged 25 to 70. Most had bands on their necks, including one who had a rope around his neck. Most of the bodies wore civilian clothing, but some were in uniforms, suggesting they were Palestinian fighters.

Hamad said the Red Cross provided names for only three of the dead, leaving many families uncertain of their relatives’ fate.

Israel’s war on Gaza has killed nearly 68,000 Palestinians since October 2023, according to the Health Ministry. Palestinian officials say the true toll could be far higher, with tens of thousands of bodies believed to be under the rubble.

Thousands more people are missing, according to the Red Cross and Palestinian Central Bureau of Statistics.

Rasmiya Qudeih, 52, waited outside Nasser Hospital, hoping her son would be among the 45 bodies transferred from Israel on Wednesday.

He vanished on October 7, 2023, the day of the Hamas-led attack. She was told he was killed by an Israeli strike.

“God willing, he will be with the bodies,” she said.

The Health Ministry released a video showing medical workers examining the bodies, saying the remains would be returned to families or buried if left unidentified.

Rights groups and a United Nations Commission of Inquiry have accused Israel of committing genocide in Gaza, and South Africa has filed a case alleging Israel committed genocide at the International Court of Justice. Israel denies the accusations.
