The Foreign Ministry of Qatar announced that Mossad chief David Barnea flew back to Israel on Tuesday, but negotiations will continue.

According to spokesperson Majed al-Ansari, Israel's technical teams remain in Qatar to examine the details of a potential deal after the principal negotiators have discussed the "main issues". "We expect that the counter-proposal will be presented to Hamas, but this is not the final step in the process," he said.

"I don't think we are at a moment where we can say we are close to a deal. We are cautiously optimistic because talks have resumed, but it's too early to announce any successes," the diplomat added.
