According to report, the Israeli prime minister's office believes 135 hostages remain in Gaza.
Israel cancelled a planned trip of Mossad director David Barnea to Qatar to restart talks on a possible second hostage release deal, CNN reported citing a source.
Mossad director David Barnea will not travel to the Qatari capital Doha, where previous talks on the release of hostages held by Hamas operatives in Gaza have taken place, the source said.
Earlier on Wednesday, Israel's Channel 13 first reported that the Israeli war cabinet, led by Prime Minister Benjamin Netanyahu, had called off the trip and that senior Israeli officials would not go to Qatar to restart negotiations.
Around 240 people, from infants to octogenarians, were taken hostage during Hamas' attack on Israel on October 7. Although dozens have been freed, many more remain missing, presumed to be held by the Palestinian operative organization and other groups in Gaza, following the breakdown of a temporary truce last month.
According to CNN, the Israeli prime minister's office believes 135 hostages remain in Gaza, out of whom 115 are alive.
Also, formal negotiations have not resumed since hostage talks that had been taking place in Doha broke down earlier this month.
But Israel, the US and Qatar have continued to discuss ways to try to jump-start the discussions, CNN reported citing multiple sources.
Families of some of the Israeli hostages were outraged by the decision to cancel Barnea's trip and demanded answers. "We are fed up with the indifference and deadlock," they said in a statement.
"The families were shocked by the report on the rejection of the Director of Mossad's request to formulate an agreement for the release of the hostages," the statement added. "This announcement comes in addition to the ignoring of the parents' request to meet with the Prime Minister and the Defense Minister, which have not yet been answered".
Notably, Barnea has been leading the hostage negotiations for Israel while his American counterpart, CIA Director Bill Burns, has done the same for the US.
Eight American citizens are believed to be among the hostages and the US has played a mediating role alongside Qatar, which has led engagement with Hamas.
Earlier on Wednesday, the families of the American hostages met with President Joe Biden in Washington. According to a family member, they also went to the CIA to meet with Burns. A US official confirmed the CIA meeting.
On Wednesday, a source familiar with the negotiation efforts told CNN that Hamas has been unresponsive to overtures made in recent days to try to restart the hostage talks.
Qatar has relayed to Hamas new ideas to try to get more hostages out of Gaza, including a potential deal that would include the release of not just the remaining women hostages, men as well, CNN reported citing one source familiar with the efforts and a senior US official.
"There's not an active negotiation, but there's a real exploration of ideas for how to get this going," the senior US official said.
