Israel and the Palestinian Hamas movement may have overcome differences in Gaza ceasefire talks in Qatar, but reaching an agreement will take more than a few days, Israeli officials said, Reuters reports.

A new attempt by the United States, Qatar, and Egypt to halt hostilities in the devastated Gaza Strip gained momentum on Sunday, when the sides began indirect talks in Doha, and Israeli Prime Minister Benjamin Netanyahu traveled to Washington.

Netanyahu met on Monday with US President Donald Trump, who said the previous day that a ceasefire and hostage release deal could begin this week. The Israeli leader is due to hold talks with Vice President JD Vance on Tuesday.

White House press secretary Karoline Leavitt told reporters that Steve Witkoff, the US Special Envoy for the Middle East who played a key role in developing the ceasefire proposal, would travel to Doha this week to participate in the talks.

The ceasefire proposal calls for a phased release of hostages, a withdrawal of Israeli forces from parts of Gaza, and further talks to end the war altogether.

Hamas has long insisted on a complete cessation of hostilities before the remaining hostages are released. Israel, in turn, has demanded that the fighting continue until all hostages are released and the Hamas structure is dismantled. At least 20 of the 50 hostages remaining in Gaza are believed to be still alive.

Palestinian sources said on Monday that differences remained between the parties over the provision of humanitarian aid to Gaza.

Senior Israeli officials told reporters in Washington that finalizing the Doha agreements could take more than a few days, but did not elaborate on the contentious issues. Another Israeli official said progress had been made on a number of issues.
