Talks are expected to be held in Doha, Qatar, starting as early as Friday, according to a senior Biden administration official.

The Mossad director is expected to meet with Qatari Prime Minister Mohammed bin Abdulrahman Al-Thani for discussions aiming to bring the parties closer to a deal in Gaza, according to a source with knowledge of the talks.

Those negotiations are expected to last two to three weeks, the Israeli source said, to resolve issues such as the identities of Palestinian prisoners to be released, the exact ratio of prisoners to hostages and the technical sequencing of the releases.

Basem Naim, a member of Hamas’ political bureau, told CNN, “there is nothing official about an effective agreement for ceasefire. The enemy’s media are talking about sending a delegation to Egypt, but there is nothing official or any details. Negotiations did not start yet.”

“We are also waiting for a positive response from the Israeli side, which will initiate negotiations into details of the deal,” Naim added. “We have no information about any delegation visiting Cairo.”

Netanyahu spoke Thursday with US President Joe Biden to discuss the progress in the negotiations and the Israeli Cabinet was set to meet Thursday evening.

The call focused on the details of the hostage and ceasefire deal, the senior Biden administration official said, adding that there seems to be a “pretty significant opening” for the hostage deal to be agreed upon by all the involved groups.

When asked if the administration believes that Netanyahu is playing politics and could try to sabotage the deal, the official said that the deal is structured in a way that “fully protects Israel’s interests.”

The official added that Biden will have the opportunity to talk about the deal with other world leaders next week during the NATO summit, which will be held in Washington, DC.
