US President Donald Trump has just posted on his Truth Social platform.
"ALL TWENTY HOSTAGES ARE BACK AND FEELING AS GOOD AS CAN BE EXPECTED," the post says.
"A big burden has been lifted, but the job IS NOT DONE. THE DEAD HAVE NOT BEEN RETURNED, AS PROMISED!" he adds.
So far, four of the 28 deceased hostages have been returned to Israel. The son of a hostage whose body is still in Gaza told the BBC earlier that the US and others involved in the ceasefire deal needed to "show Hamas that this is not acceptable".
"Phase Two begins right NOW!!!" Trump adds, referring to the next stage of negotiations.
There are likely to be multiple points of contention during the negotiations over later phases of the deal, including over calls for Hamas to lay down its weapons - a possibility the group is reported to have dismissed.
