Hamas leaders held talks with Egyptian security officials on Sunday in a fresh push for a ceasefire in the Gaza war, two Hamas sources said, and Israeli Prime Minister Benjamin Netanyahu was set to convene his security cabinet on the matter, two Israeli officials said.
The Hamas visit to Cairo was the first since the United States announced on Wednesday it would revive efforts in collaboration with Qatar, Egypt and Turkey to negotiate a ceasefire in Gaza, that would include a hostage deal.
White House national security advisor Jake Sullivan said he thought the chances of a ceasefire and hostage deal in Gaza were now more likely.
"(Hamas) are isolated. Hezbollah is no longer fighting with them, and their backers in Iran and elsewhere are preoccupied with other conflicts," he told CNN on Sunday.
"So I think we may have a chance to make progress, but I'm not going to predict exactly when it will happen ... we've come so close so many times and not gotten across the finish line."
Fighting raged on meanwhile in the enclave and the head of the United Nations Palestinian refugee agency (UNRWA) said it had to halt aid deliveries through one crossing a day after armed gangs inside Gaza seized food from a truck convoy.
Hamas is seeking a ceasefire agreement that would end the war while Israel has said the war will only end when Hamas is eradicated.
