The remains of a slain hostage were transferred into Israeli territory by the IDF on Monday evening, and arrived at the National Institute for Forensic Medicine in Abu Kabir at approximately midnight.
Military representatives accompanied the families to the institute where forensic scientists have begun the identification process.
"The IDF requests that the public act with sensitivity and wait for the official identification, which will first be provided to the families," a statement from the IDF and Shin Bet (Israel Security Agency) read.
Earlier, Hamas announced that the handover would occur at 9 p.m. The actual handover happened at around 10 p.m.
A member of Hamas's Izzadin al-Qassam Brigades told Al Jazeera earlier in the day that the remains had been discovered during excavation efforts in the Tuffah neighborhood in Gaza City. The Gaza City area is currently on the Hamas side of the Yellow Line as dictated by the ceasefire deal.
Separately, Hamas told Arab mediators that it is working to excavate between seven and nine bodies of slain hostages from the Gaza Strip, Saudi network Asharq News reported on Monday.
The Palestinian terror organization confirmed the locations of the bodies in different areas in the Gaza Strip, a source familiar with the search told Asharq.
No specific date for the handover has been set.
The source added that as soon as the remains are excavated, Hamas will hand them over to the Red Cross. However, the source did not say if all of the remains will be released in one handover.
Asharq reported that several days ago, Hamas requested through mediators that the IDF withdraw from "certain areas outside the so-called yellow line" in southern Gaza in order to finish looking for the hostages' remains.
Trump gives Hamas 48-hour deadline to speed up hostage body return process
The Asharq report comes after US President Donald Trump warned Hamas on Saturday that the terror group needed to work more quickly to return the hostages' remains.
"Hamas is going to have to start returning the bodies of the deceased hostages, including two Americans, quickly," he wrote.
Trump gave Hamas a 48-hour deadline to return more hostage bodies.
"Let’s see what they do over the next 48 hours. I am watching this very closely," he affirmed.
