The latest round of Gaza cease-fire talks ended in Cairo after “in-depth and serious discussions,” the Hamas militant group said Sunday, reiterating key demands that Israel again rejected. After earlier signs of progress, the outlook appeared to dim as Prime Minister Benjamin Netanyahu vowed to resist international pressure to halt the war. Defense Minister Yoav Gallant claimed Hamas wasn't serious about a deal and warned of “a powerful operation in the very near future in Rafah and other places across all of Gaza " after Hamas attacked Israel's main crossing point for delivering badly needed humanitarian aid, killing three soldiers.
