An Israeli airstrike on a school sheltering displaced families in northern Gaza killed at least 10 people on Wednesday, while another hit a children's hospital, medics said, as three European leaders called on Israel to end its blockade on aid.

The war began when Hamas-led militants attacked southern Israel on Oct. 7, 2023, killing some 1,200 people, mostly civilians, and abducting 251. Fifty-nine hostages are still inside Gaza, 24 of whom are believed to be alive, after most of the rest were released in ceasefire agreements or other deals.
