Qatar, Israel hostage talks show positive signs but no deal struck: Reuters

Qatar's prime minister met with the heads of Israel's Mossad spy agency and the U.S. Central Intelligence Agency (CIA) in Warsaw on Monday for resumed hostage negotiations. 

While the resumed talks showed positive signs, there is no expectation of an imminent cease-fire deal between Israel and Hamas , Reuters reported citing sources briefed on the diplomatic efforts.

The leaders met in Poland’s capital to discuss a potential new deal to secure the release of Israeli hostages held by Hamas in Gaza in exchange for a potential release of Palestinians in Israeli prisons and a humanitarian pause in the fighting.

"The talks were positive with negotiators exploring and discussing different proposals in an attempt to progress on negotiations," the source said. "An agreement is not expected imminently however."

The office of Israel's prime minister and the CIA declined to comment to Reuters.

Qatar is serving as a mediator between Israel and Hamas. The Arab nation has said it is working to restore a humanitarian cease-fire agreement that ended last month.

During the previous week-long truce, Hamas released more than 100 hostages in exchange for 240 Palestinian prisoners held in Israel.
