DOHA: Hamas said Friday the Palestinian group rejected "new conditions" in a Gaza ceasefire plan the United States presented after two days of talks with Israeli negotiators in Qatar.

As international pressure mounted for a ceasefire after more than 10 months of war between Israel and Hamas in the Gaza Strip, US President Joe Biden said: "We are closer than we have ever been."

US Secretary of State Antony Blinken is to travel to Israel this weekend to advance the latest proposal, the State Department said.

"Secretary Blinken will underscore the critical need for all parties in the region to avoid escalation or any other actions that could undermine the ability to finalise an agreement," it said.

Washington has joined its European allies in pushing for a swift ceasefire in Gaza since the July 31 killing of Hamas political leader Ismail Haniyeh in an attack in Iran blamed on Israel prompted threats of retaliation and fears of a wider Middle East war.

Egyptian, Qatari and US mediators have been seeking to finalise details of a framework initially outlined by Biden in May, and which he said Israel had proposed.

But months of talks have so far failed to pin down the details of a truce and hostage release deal.

The mediators said that the two days of talks in Doha were "serious and constructive".

In a joint statement, they said the United States had presented a "bridging proposal" that sought to secure a rapid deal at a new round of talks in Cairo next week.

Hamas swiftly announced its opposition to what it called "new conditions" from Israel in the latest plan.

Israeli Prime Minister Benjamin Netanyahu called on the mediators to put "pressure" on Hamas "to accept the May 27 principles", referring to Biden's framework.

Western ally Jordan however put the blame squarely on Netanyahu for blocking a deal. "He must be directly and effectively pressured by everyone who wishes to see this through to completion," Foreign Minister Ayman Safadi said.

An informed source told AFP that the conditions Hamas objected to included keeping Israeli troops inside Gaza along the territory's border with Egypt, veto rights for Israel on the Palestinian prisoners to be exchanged for Israeli hostages, and the ability to deport some prisoners rather than send them back to Gaza.

Diplomatic pressure on Israel to agree a truce has increased in recent weeks.

Hamas officials, some analysts and protesters in Israel have accused Netanyahu of prolonging the war.

British Foreign Secretary David Lammy and his French counterpart Stephane Sejourne held talks in Israel Friday to urge a Gaza ceasefire.

Britain's foreign ministry said the two ministers would "stress there is no time for delays or excuses from all parties on a ceasefire deal".

Israeli Foreign Minister Israel Katz told his visiting counterparts he expects foreign support "in attacking" Iran if it strikes Israel in revenge for Haniyeh's killing.

Sejourne replied that it would be "inappropriate" to discuss responding to any attack while diplomacy is in high gear to stop it happening.

A senior US official, speaking to reporters on condition of anonymity, said Iran would face "cataclysmic" consequences if it strikes Israel.

A deadly attack by Israeli settlers in the occupied West Bank late Thursday drew international condemnation and calls for sanctions, including against government ministers, over the upsurge in settler violence against Palestinians particularly since the Gaza war began.

The Israeli military said "dozens of Israeli civilians, some of them masked", entered the village of Jit, west of Nablus, and "set fire to vehicles and structures in the area, hurled rocks and Molotov cocktails". A Palestinian man was shot dead.

Villager Hassan Arman said the settlers were armed with knives, a machine gun and a silencer.

The Palestinian foreign ministry described the attack as "organised state terrorism".

The British foreign minister called the attack "abhorrent". The French minister said it was "unacceptable".

The European Union's top diplomat Josep Borrell said he would propose sanctions against Israeli government "enablers" of Jewish settler violence.

"Day after day, in an almost total impunity, Israeli settlers fuel violence in the occupied West Bank, contributing to endanger any chance of peace," Borrell posted on X.

"The Israeli government must stop these unacceptable actions immediately," he wrote.

Israel's far-right Finance Minister Bezalel Smotrich, a proponent of West Bank settlements, was quick to join other Israeli leaders in condemning Thursday's attack by "criminals".

Hamas's unprecedented October 7 attack on Israel triggered the war that resulted in the deaths of 1,198 people, mostly civilians, according to an AFP tally of Israeli official figures.

They also seized 251 hostages, 111 of whom are still held in Gaza, including 39 the military says are dead. More than 100 were freed during a one-week truce in November.

On Thursday, the toll from Israel's retaliatory military campaign in Gaza topped 40,000, according to the health ministry in Gaza.

As the Gaza truce talks were underway, bombs have continued to fall in the Palestinian territory.

The Israeli military on Friday issued new evacuation orders for parts of Deir al-Balah, in central Gaza, and Khan Yunis in the south.

"During each round of negotiations, they exert pressure by forcing evacuations and committing massacres," Issa Murad, a Gazan displaced to Deir al-Balah, said of the Israeli forces.
