CAIRO — Turbulent negotiations to broker a temporary truce in the Gaza Strip are continuing against the backdrop of fresh Israeli attacks on Palestinian militants.

U.S. Secretary of State John Kerry met twice Friday in Cairo with U.N. chief Ban Ki-Moon and Egyptian Foreign Minister Sameh Shukri to try to nail down a deal to bring a week-long pause in the fighting and begin as soon as this weekend.

It’s part of a plan to phase in a lasting cease-fire between Israel and the Hamas militant group in the three-week war.

Two diplomats close to the negotiations said a deal had not yet been reached but spoke on condition of anonymity because they were not authorized to be named.

Kerry, Ban and Shukri were expected to brief the media later Friday.
