A video this week captured Hamas fighters in Gaza executing Palestinian rivals as the militant group tries to assert that it is still the dominant force in the territory after two years of war with Israel.

The prospect of rebuilding homes, businesses and all the institutions and services needed for a return to normal life in Gaza is daunting by any measure: the UN estimates that the damage amounts to $70bn.

Even before the outbreak of war, Gazans faced a number of environmental concerns. “The situation in Gaza on the ground prior to October 7, 2023 was, from an environmental and humanitarian point of view, not good,” says David Lehrer, Arava Institute’s director of applied environmental diplomacy.

Violent clashes have erupted between Hamas and rival groups in several areas across Gaza, including an incident that culminated in an apparent public execution, as worries grow about the security situation following Israel’s withdrawal from parts of the territory.

At least 27 people have been killed in one of the most violent internal confrontations since Israeli troops withdrew.

The United Nations is seeking a dramatic boost in humanitarian aid for Gaza, saying the hundreds of relief trucks cleared to enter the devastated enclave under a ceasefire were nowhere near the thousands needed to ease a humanitarian disaster.

Monday’s release of the last 20 living Israeli hostages and nearly 2,000 Palestinian prisoners and detainees marks a pivotal moment in the war in Gaza , though it’s unclear whether it signals the end of conflict.

The Israeli military said its troops had opened fire to "remove the threat" of people approaching them across the "yellow line" where forces had retreated under Trump's deal.

As the ceasefire began, Israel released more than 1,900 Palestinian prisoners in exchange for hostages freed by Hamas. Amid the rubble in Gaza, families begin to find their way home.
