Citing Egyptian sources, Al-Qahera News reported that Head of the General Intelligence Service Abbas Kamel is taking part in the talks underway in Doha with Qatari, US, and Israeli officials to discuss an extension in the truce between Israel and Hamas.
The leaders of the US Central Intelligence Agency and Israel's Mossad were scheduled to meet Qatari Prime Minister Mohammed bin Abdulrahman Al Thani, the source told AFP, adding that Egyptian officials were also taking part.
"The director of the CIA and the director of the Israeli National Intelligence Agency are in Doha to meet with the Qatari prime minister," the source told AFP, requesting anonymity due to the talks' sensitivity.
The discussions aim "to build on the progress of the extended humanitarian pause agreement and to initiate further discussions about the next phase of a potential deal," the source added.
Egypt and Qatar have been engaged in intense negotiations, with support from the United States, to extend the truce in Gaza, mediated by Cairo and Doha, that was originally due to last four days.
Qatar announced late on Monday, the day of the truce's expiry, that successful talks with Israel and Hamas had resulted in a two-day extension.
Over the initial four-day pause, 50 captives -- all women and children -- were freed in return for 150 Palestinian prisoners held by Israel - all minors and women.
On Tuesday, Qatar's foreign ministry spokesman said the mediator would use the extension to work towards a "sustainable truce" between Israel and Hamas.
"Our main focus right now, and our hope, is to reach a sustainable truce that will lead to further negotiations and eventually to an end... to this war," Majed Al Ansari told reporters.
"However, we are working with what we have. And what we have right now is the provision to the agreement that allows us to extend days as long as Hamas is able to guarantee the release of at least 10 hostages."
Ansari confirmed the truce would continue with the release of 20 further captives and more Palestinian prisoners.
"We are hopeful that in the next 48 hours, we will be getting more information from Hamas regarding the rest of the hostages," he added.
The spokesman said "minimal breaches" in recent days had not "harmed the essence of the agreement".
