Palestinians exhumed at least 190 bodies from a mass grave at the Nasser Hospital in Khan Younis city in the southern Gaza Strip, the state news agency Wafa reported on Sunday.
The bodies were found following Israeli troop withdrawal from the city on April 7 after a military offensive there, Wafa said.
It said women and children made up the majority of the victims in the mass grave.
According to the broadcaster, around 500 people have been reported missing following the Israeli offensive on Khan Younis.
There was no comment from the Israeli military on the report.
Israel has launched a brutal offensive on the Gaza Strip since Oct. 7, 2023 following a Hamas attack that killed nearly 1,200 people.
Nearly 34,100 people have since been killed and 77,000 others injured mass destructions and severe shortages of necessities.
The Israeli war has pushed 85% of Gaza's population into internal displacement amid acute shortages of food, clean water, and medicine, while 60% of the enclave's infrastructure has been damaged or destroyed, according to the UN.
