The head of the US intelligence agency has left for Qatar amid a deadlock in Israel-Hamas talks on a pause in fighting in Gaza and the release of hostages.
Reuters news agency reported on Sunday that CIA Director William Burns was traveling to Doha to hold an emergency meeting with Qatar's prime minister.
Hamas delegates have left Egypt, without an agreement with Israel. The group demanded a complete ceasefire.
Reuters quoted an official as saying that Burns' visit to Qatar is "aimed at exerting maximum pressure on Israel and Hamas to continue negotiating."
Qatar and Egypt have been mediating the talks. The top leader of Hamas' political wing is based in Qatar.
Also on Sunday, Israeli forces continued to attack the southern Gaza city of Rafah. Reuters says at least 19 people were killed.
