The Israeli Prime Minister's Office says talks among intelligence chiefs aimed at brokering a hostage deal between Israel and Hamas have been held in Europe but gaps still remain.
The prime minister's office said in a statement on Sunday that the meeting included the head of Israel's Mossad intelligence service, US Central Intelligence Agency Director William Burns, the Qatari prime minister and other officials.
The statement says the talks were constructive, but there are still significant gaps which the sides will continue to discuss at additional meetings this week.
One potential deal is said to require Israel to pause its military operations in Gaza for about two months and free Palestinian detainees in exchange for the release of the hostages held by Hamas.
But negotiations between the two sides are apparently encountering difficulties as Hamas is demanding a complete ceasefire while Israel says it is only ready to accept a pause.
