Fighting has raged in the besieged Gaza Strip since Biden said Israel was offering a new roadmap towards a full ceasefire.

Qatari, Egyptian and US mediators called on Israel and Hamas on Saturday to “finalise” the truce deal outlined by US President Joe Biden, as Israeli forces pounded Rafah in southern Gaza.

Fighting has raged in the besieged Gaza Strip since Biden said Israel was offering a new roadmap towards a full ceasefire.

But Israeli Prime Minister Benjamin Netanyahu has since insisted his country would pursue the war until it had achieved all its aims.

He reiterated that position on Saturday, saying that "Israel's conditions for ending the war have not changed: the destruction of Hamas's military and governing capabilities, the freeing of all hostages and ensuring that Gaza no longer poses a threat to Israel".

Hamas, meanwhile, said it "views positively" the Israeli plan laid out by Biden on Friday.

In a joint statement, Qatar, the United States and Egypt said that "as mediators in the ongoing discussions to secure a ceasefire in Gaza and the release of hostages and detainees", they "call on both Hamas and Israel to finalise the agreement embodying the principles outlined by President Joe Biden".

The US president said Israel's three-stage offer would begin with a six-week phase that would see Israeli forces withdraw from all populated areas of Gaza.

It would see the "release of a number of hostages" in exchange for "hundreds of Palestinian prisoners" held in Israeli jails.

Israel and the Palestinians would then negotiate for a lasting ceasefire, with the truce to continue so long as talks are ongoing, Biden said.

"It's time for this war to end, for the day after to begin."
