A senior US official, however, described the talks as "constructive", saying they were conducted in a spirit on all sides to reach "a final and implementable agreement." "The process will continue over the coming days through working groups to further address remaining issues and details," said the official, speaking on the condition of anonymity, adding that the teams would remain in Cairo.

Months of on-off talks have failed to produce an agreement to end Israel's devastating military campaign in Gaza or free the remaining hostages seized by Hamas in the militant group's Oct. 7 attack on Israel that triggered the conflict.
