Israel, Hamas truce and hostage release delayed

Israel said a four-day Gaza truce and hostage release will not start until at least Friday, stalling a breakthrough deal to pause the brutal and bloody seven-week-old war.

Israeli national security adviser Tzachi Hanegbi indicated the release of at least 50 Israeli and foreign hostages held by Hamas was on track, but would not happen until Friday at the earliest.

"The contacts on the release of our hostages are advancing and continuing constantly," he said in a statement. "The start of the release will take place according to the original agreement between the sides, and not before Friday."

A second Israeli official said that a halt in fighting would also not take place on Thursday, as had been expected.

The delay is a hammer blow to families desperate to see their loved ones return home, and to two million-plus Gazans praying for an end to 47 days of war and destruction.

The complex and carefully choreographed deal saw Israel and Hamas militants agree a four-day truce, during which at least 50 hostages taken in the deadly October 7 attacks would be released. Three Americans, including three-year-old Abigail Mor Idan, were among the hostages earmarked for release.

For every 10 additional hostages released, there would be an extra day's "pause" in fighting, an Israeli government document said. In turn, Israel would release at least 150 Palestinian women and children and allow more humanitarian aid into the coastal territory after weeks of bombardment, heavy fighting and a crippling siege.

It was not immediately clear what caused the delay, or whether it signalled a serious breakdown in implementation.

The deal had been expected to come into force from Thursday, despite fierce opposition from some in Israel's hard-right government. Hardline interior minister Itamar Ben-Gvir described the deal as a "historic mistake" that would embolden Hamas and risk the lives of Israeli troops.

An estimated 240 hostages were taken by Hamas and other Palestinian gunmen during bloody raids into Israel on October 7, which are also believed to have killed 1,200 people. The shock attack prompted a blistering Israeli offensive into Hamas-run Gaza, which authorities there say has killed more than 14,000 people.

Most casualties on both sides are said to be civilians, although exact tolls could not be independently verified.

Israel's embattled Prime Minister Benjamin Netanyahu has backed the agreement with Hamas -- brokered by Qatar, the United States and Egypt -- but vowed it will be temporary and will not end the campaign to destroy Hamas.

"We are winning and will continue to fight until absolute victory," he said on Wednesday, vowing to secure Israel from threats emanating from Gaza and Lebanon, home to Iranian-backed Hezbollah militants.

Tensions rose on Israel's northern border early Thursday, after Hezbollah said five fighters, including the son of a senior lawmaker, had been killed.
