Mr Netanyahu clarified that the body returned was that of a Gaza resident, not Ms Bibas.
According to Hamas, the deceased include a mother and her two young sons: Shiri Bibas and her boys, Ariel and Kfir.
The Israeli Defence Force, in a tweet, announced the release of Israeli hostages held in captivity for 498 days.
Mr Netanyahu’s comments were made in response to the threat made by Hamas on Monday postponing the next round of hostage releases.
Another exchange of hostages and prisoners is set for next weekend.
Hamas has rejected U.S. President Donald Trump’s proposal to relocate Palestinians from the Gaza Strip to Egypt and Jordan.
The spokesperson for Israel defence said that their mission was not over until every single hostage was released.
The office of Israeli Prime Minister Benjamin Netanyahu said the four women are all soldiers.
On January 15, Israel and Hamas agreed to a ceasefire-for-hostages deal after intensive mediation by Qatar, Egypt, and the United States.
According to a UN report released in 2024, rebuilding Gaza’s shattered homes will take at least until 2040 but could drag on for many decades.
