Israel's Netanyahu heckled by hostage families during parliament address

"Now! Now!" the families chanted from the gallery when Netanyahu said Israeli forces first needed to increase military pressure on Gaza's Hamas rulers.

"We wouldn't be able to secure the release of hostages without military pressure," he said.

Netanyahu said he spoke to Israeli field commanders who said they needed "more time" to finish the mission.

"We won't stop until victory," Netanyahu said over the cries of protesters.

Israel says 129 hostages, abducted on October 7 when Hamas gunmen attacked southern Israel, are still held in the Palestinian territory.

"We, my colleagues and I, aren't sparing any effort," Netanyahu added, to return "all of our hostages home".

Netanyahu's address came after his Likud party reported that he visited the Gaza Strip on Monday and vowed to step up the army's assault in the Palestinian territory.

"I just came back from Gaza," he said, according to a Likud party statement.

"We're not stopping, we're continuing to fight and we're intensifying the fighting in the coming days. It's going to be a long war that's not close to ending."
