Hamas has returned the bodies of four more deceased hostages, the Israel Defense Forces (IDF) has said.

The Red Cross retrieved the remains in coffins and handed them over to the Israeli military late on Tuesday night.

The transfer came after Israel warned it would restrict aid into Gaza until Hamas returned the bodies of all 28 deceased hostages. The Palestinian armed group handed back 20 living and four deceased hostages on Monday.

The remains of 45 deceased Palestinians who had been held in Israel were returned to Gaza on Tuesday, the Red Cross said in a statement.

US President Donald Trump's ceasefire plan, which both Israel and Hamas accepted, envisaged the handover of all 48 hostages would be completed by noon on Monday.
