A spokesman for Hamas' armed wing said on Sunday its fighters had captured Israeli soldiers during fighting in Jabalia in northern Gaza on Saturday, though the Israeli military denied the claim.
The Hamas armed wing spokesman did not say how many soldiers had been abducted, and showed no proof of the claim.
"Our fighters lured a Zionist force into an ambush inside a tunnel ... The fighters withdrew after they left all members of the force dead, wounded, and captured," Abu Ubaida, the spokesman for Al Qassam Brigades, said in a recorded message broadcast by Al Jazeera early on Sunday.
The Israeli military on Sunday denied the claim by Hamas' armed wing.
"The IDF (Israeli Defence Forces) clarifies that there is no incident in which a soldier was abducted," the military said in a statement.
The comments by Abu Ubaida came hours after prospects for a resumption of mediated Gaza ceasefire talks grew on Saturday.
An official with knowledge of the matter said a decision had been taken to resume the talks next week after the chief of Israel's Mossad intelligence agency met the head of the CIA and the prime minister of Qatar.
The source, who declined to be identified by name or nationality, said it had been decided that "in the coming week negotiations will open based on new proposals led by the mediators, Egypt and Qatar and with active U.S. involvement."
A Hamas official later denied Israeli media reports the talks would resume in Cairo on Tuesday, telling Reuters: "There is no date."
After more than seven months of war in Gaza, the mediators have struggled to secure a breakthrough, with Israel seeking the release of hostages held by Hamas and Hamas seeking an end to the war and a release of Palestinian prisoners in Israel.
Nearly 36,000 Palestinians have been killed in Israel's offensive, Gaza's health ministry says. Israel began the operation in response to Hamas-led militants attacking southern Israeli communities on Oct. 7, killing around 1,200 people and seizing more than 250 hostages, according to Israeli tallies.
