There have been many potential turning points in this war, and every time Israel has remained determinedly on the path it's set: to destroy Hamas.

AFP journalists on the ground early Tuesday reported fresh Israeli strikes overnight in the southern Gaza border city, where an Israeli attack targeting two senior Hamas members on Sunday night sparked a fire that ripped through a displacement centre, killing 45, according to Gaza health officials.

The attack prompted a wave of international condemnation, with Palestinians and many Arab countries calling it a "massacre". Israel said it was looking into the "tragic accident".

"There is no safe place in Gaza. This horror must stop," UN Secretary-General Antonio Guterres posted on social media.

UN humanitarian chief Martin Griffiths pointed to the widespread warnings of civilian deaths that circulated ahead of Israel's incursion into Rafah, saying in a statement: "We've seen the consequences in last night's utterly unacceptable attack."

"To call it 'a mistake' is a message that means nothing for those killed, those grieving, and those trying to save lives," he added.
