"The horror of that dark day will be forever seared in the memories of us all," UN Secretary General Antonio Guterres said.

SHEIKH, Egypt (Reuters) -Hamas said on Tuesday it wants to reach a deal to end the war in Gaza based on U.S. President Trump's plan but still has a set of demands, a statement signalling that indirect talks with Israel in Egypt could be difficult and lengthy.

At least 450 activists were aboard the flotilla, a coalition of several vessels seeking to deliver humanitarian aid to the blockaded Palestinian territory. Israeli forces detained them last week, and by Monday had deported Thunberg and 170 others to countries including Greece and Slovakia.

On the second anniversary of the Hamas-led attack on Israel of Oct. 7, 2023, the leaders of Israel and Hamas are pushed by Arab countries and the U.S. toward a potential end to the war.

Palestinian health authorities say Israel's two-year-old ground and air campaign against Hamas militants in the Gaza Strip has killed more than 67,000 people, with nearly a third of the dead under the age of 18.

Peace talks between Israel and Hamas resumed at an Egyptian resort city on Tuesday, the two-year anniversary of the militant group's surprise attack on Israel that triggered the bloody conflict that has seen tens of thousands of Palestinians killed in Gaza.

Two years since the war in Gaza began, thousands of Palestinians there are looking for relatives who have gone missing in one of the most destructive conflicts of the past decades.

The Vatican's top diplomat sharply criticised Israel's "ongoing massacre" in Gaza in comments published on Monday - one of the Catholic Church's strongest condemnations of Israel's war against the militant group Hamas.
