Israeli Prime Minister Benjamin Netanyahu is asking for forgiveness from the families of the six slain hostages whose bodies were recovered this weekend.

"I ask you for forgiveness that we did not succeed to bring your loved ones back alive. We were close, but we did not succeed," Netanyahu said at a Monday news conference.

Netanyahu again said the Israel Defense Forces must maintain a presence on the Egyptian border, but he said the IDF does not need a "large" presence of forces there. It needs groups of forces in key areas all along the border, he said. Netanyahu also reiterated that the IDF must maintain a presence in the Philadelphi corridor to reach the goals of the war.

When asked how he would define "total victory" in the war, Netanyahu responded, "When Hamas no longer rules Gaza -- we throw them out. I would define the end of the war of World War II when the Nazis no longer ruled Germany. To do that you need to have a military victory and you have to have also a political victory to destroy their governance."

Netanyahu also said that international "pressure" must be directed at Hamas, not Israel.

"These murderers executed six of our hostages, they shot them in the back of the head. And now after this we're asked to show seriousness, we're asked to make concessions? What message does this send Hamas?" he said.

Netanyahu added, "I don't believe President [Joe] Biden or anyone serious about achieving peace and achieving the release [of hostages] can seriously ask Israel to make these concessions. We've already made them. Hamas has to make concessions."

A Hamas military spokesman said in a new statement the Israeli hostages won't be freed by force.

"Netanyahu's insistence on freeing the prisoners through military pressure instead of concluding a deal will mean their return to their families in coffins, and their families will have to choose between dead or alive," the spokesperson said.

President Joe Biden told reporters "we’re still negotiating" when asked if there will be a final hostage and cease-fire deal proposed this week.

Asked what he wants Israeli Prime Minister Benjamin Netanyahu to do, Biden replied, "We’re in the middle of negotiations."

"We’re still in negotiations. Not with him [Netanyahu], with my colleagues from Qatar and from Egypt," Biden said.

Earlier on Monday, Biden and Vice President Kamala Harris met with the U.S. hostage deal negotiating team in the Situation Room.

National security adviser Jake Sullivan spoke on the phone Monday morning with Israeli Minister of Strategic Affairs Ron Dermer and Qatari Prime Minister and Minister of Foreign Affairs Mohammed bin Abdulrahman Al Thani, a U.S. official said. They discussed efforts to conclude a deal for the release of the hostages and for a cease-fire in Gaza, the official said.

Protesters broke through barriers near Israeli Prime Minister Benjamin Netanyahu’s residence in Jerusalem on Monday as they demanded progress on a deal to return the hostages in Gaza.

Monday marks the second day of large protests across Israel after six murdered hostages were recovered in Gaza this weekend.

Israeli Defense Minister Yoav Gallant said in a statement he was "deeply disheartened" to learn of the United Kingdom’s new restrictions on some arms exports to Israel.

"This comes at a time when we fight a war on 7 different fronts -- a war that was launched by a savage terrorist organization, unprovoked," Gallant said. "At a time when we mourn 6 hostages who were executed in cold blood by Hamas inside tunnels in Gaza. At a time when we fight to bring 101 hostages home."

U.K. Foreign Secretary David Lammy told Parliament on Monday about 30 of 350 export licenses are suspended because "there does exist a clear risk that they might be used to commit or facilitate a serious violation of international humanitarian law."
