Israel will allow Gaza's Rafah border crossing with Egypt to open on Wednesday and increase the amount of humanitarian aid coming into the enclave, public broadcaster Kan reported, after Hamas handed over more bodies of deceased hostages.

Despite widespread calls for his release, Abu Safiya was not among the hundreds of Palestinian detainees and prisoners freed Monday in exchange for 20 hostages held by Hamas.

Israel's military said it opened fire on "several suspects" who were spotted crossing a boundary that troops pulled back to under the ceasefire deal.
