The first phase, spanning a 42-day ceasefire, would see the exchange of 33 Israeli hostages in Gaza for Palestinians held in Israeli prisons, U.S. officials said.

The terms of a deal between Israel and Hamas for a ceasefire in Gaza and the release of hostages are being finalised, a Palestinian official familiar with the negotiations has told the BBC. It comes as White House National Security Advisor Jake Sullivan said a truce and hostage deal could be done "this week".

Negotiators were trying to clinch agreement on Tuesday on the final details of a ceasefire in Gaza after marathon talks in Qatar, with mediators and the warring sides both saying a deal was closer than ever.
