Israeli soldiers shot Palestinians near an Israel-backed food site. On Sunday, they fired at people gathering near a U.N. convoy. Both incidents were symptoms of broader problems.

At least 85 Palestinians were killed while seeking aid in one of the deadliest days for aid-seekers since the war began, Gaza's Health Ministry said.

Israeli troops are preparing for ground operations in central Gaza for the first time since the outbreak of the war in Gaza, raising hopes that some of the remaining 50 hostages may be located.

Cardinal Pierbattista Pizzaballa entered Gaza on Friday to bring aid to victims of Israel's strike on the sole Catholic church in the Palestinian enclave, while he and a Vatican official questioned Israeli explanations for the incident.

Reacting to the new GHF flag system, Ibrahiem Mohammed Abdul Raouf Al Qatrawi, a 22-year-old Palestinian, called for the total cancellation of the GHF aid system, telling ABC News on Monday that "respect and dignity" should be restored.

The GHF aid distribution scheme was established after Israel partially lifted its blockade of aid supplies into Gaza. It established four sites - called "Safe Distribution Centres (SDS)" - on the strip. Three were located in the south, near Rafah, and one in central Gaza.
