The BBC is part of a traveling press collection around the US Secretary of State’s visit to Qatar – a glittering Gulf location that belies the sense of regional crisis he is trying to resolve with a diplomatic tour taking place at breakneck speed.

There were hugs and smiles when Blinken met Qatari Prime Minister and Foreign Minister Sheikh Mohammed bin Abdulrahman Al Thani.

His country is a major player in this crisis, as it hosted the political offices of Hamas for more than a decade and served as a channel for negotiations with Israel.

Blinken appeared angry when he said in a joint press conference that they were discussing the changes requested by Hamas to the ceasefire proposal supported by the United States.

“There was an agreement on the table that was almost identical to the proposal put forward by Hamas on May 6, which is the agreement that the whole world supports, and Israel accepted, and Hamas could have answered with one word: ‘Yes.’” he said.

“Instead, Hamas waited nearly two weeks and then proposed further changes, a number of which go beyond the positions it had previously taken and accepted. As a result, the war that Hamas started… will continue, more people will suffer, and more Palestinians will suffer.” They will suffer, and more Israelis will suffer.”

Blinken did not clarify what changes he said Hamas was demanding, nor did a brief statement issued by the movement itself on Tuesday evening.

However, the statement reiterated the demand for what Hamas called “a complete cessation of the ongoing aggression against Gaza” and the complete withdrawal of Israeli forces.

Izzat Al-Rishq, a member of the Hamas political bureau, said that the response was “responsible, serious and positive” and that it opened a “broad path” to reaching an agreement.

The Israeli Prime Minister’s Office did not issue an official response.

But a statement was issued by an anonymous Israeli official, who said that Hamas “changed all the main and most important criteria” and “rejected the hostage release proposal made by President Biden.”

In a later statement on Wednesday, reported by Reuters news agency, Hamas said it had shown “complete positivity” in its efforts to reach an agreement, adding that it had urged Blinken to put “direct pressure” on Israel.

Despite the setbacks, Blinken said the United States, along with Qatar and Egypt, “will try to complete this deal.”

“I believe that these gaps can be closed. But that does not mean that they will be closed, because in the end, Hamas has to decide.”

Sheikh Mohammed said that both Hamas and Israel need to make some concessions.

He pointed out, “We are witnessing a shift in this conflict in the recent period, and there is a clear and firm call to end this war.”

Mr Blinken also said it was essential to make plans for the “day after the conflict” in Gaza as soon as possible in order to achieve a permanent end to the war.

He added: “In the coming weeks, we will put forward proposals on the main elements of the Day After Day plan, including concrete ideas on how to manage governance, security and reconstruction.”

The Israeli military launched a campaign in Gaza to destroy Hamas in response to an unprecedented attack on southern Israel on October 7, during which some 1,200 people were killed and 251 others were taken hostage.

More than 37,200 people have been killed in Gaza since then, according to the Hamas-run Health Ministry in the Strip.

The agreement reached in November saw Hamas release 105 hostages in exchange for a week-long ceasefire and about 240 Palestinian prisoners in Israeli prisons. Israel says 116 hostages are still being held, 41 of whom are presumed dead.

The first involves an initial six-week ceasefire, during which Hamas would release some hostages—including women, the elderly, the sick, and the wounded—in exchange for Israel releasing an unspecified number of Palestinian prisoners. There will also be a withdrawal of Israeli forces “from all populated areas of Gaza” and an “increase” in humanitarian aid.

The second phase will see the release of all remaining living hostages and the withdrawal of all Israeli forces from Gaza as part of a “permanent cessation of hostilities”, but the latter will remain subject to further negotiations.

During the third phase, the remains of any dead hostages will be returned and a major reconstruction plan will begin in Gaza.

While the White House is in fact trying to push the two sides toward an agreement, the Israeli leadership remains deeply skeptical about the matter.

The far-right ministers are pressuring Netanyahu to ignore Washington’s diplomacy and have threatened to withdraw from his ruling coalition and cause its collapse if the US-backed proposal goes ahead, considering it a surrender to Hamas.

The Prime Minister did not unequivocally express his support for the plan, which he acknowledged had been approved by the War Cabinet.

The actual Israeli proposal — which is said to be longer than Biden’s summary — has not been made public and it is unclear whether it differs from what the president conveyed. It was presented to Hamas days before Biden’s speech.
