JERUSALEM (Reuters) -Talks held on Sunday initiated by Qatar, the United States and Egypt to broker a hostage deal between Israel and Hamas were "constructive" but meaningful gaps remain, the Israeli prime minister's office said. "There are still significant gaps in which the parties will continue to discuss this week in additional mutual meetings," Prime Minister Benjamin Netanyahu's office said in a statement. U.S. Central Intelligence Agency Director William Burns and the head of Israel's Mossad intelligence service, David Barnea, met with Qatari Prime Minister and Foreign Minister Sheikh Mohammed bin Abdulrahman Al Thani, along with the head of Egyptian intelligence, Abbas Kamel, the statement said. Some 1,200 people were killed and 253 abducted, according to Israeli officials. The U.S. and Israeli intelligence chiefs have previously met with Qatari and Egyptian officials, helping to broker a short-lived truce in November that saw more than 100 hostages freed.
