Israel-Gaza updates: Police killed in border shooting, authorities say

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."

President Joe Biden and Vice President Kamala Harris met with the U.S. hostage deal negotiating team in the Situation Room on Monday, according to the White House.

Biden and Harris received an update from the negotiation team on the "status of the bridging proposal outlined by the United States, Qatar and Egypt" and "they discussed next steps" in the release of the hostages, the White House said.

Biden also "expressed his devastation and outrage at the murder" of Israeli-American Hersh Goldberg-Polin and five other hostages and he "reaffirmed the importance of holding Hamas’s leaders accountable," the White House said.

Officials participating in the briefing included Secretary of State Antony Blinken, CIA Director Bill Burns and national security adviser Jake Sullivan.

In an Israeli cabinet meeting, Israeli Prime Minister Benjamin Netanyahu doubled down on his stance that he will not agree to a cease-fire and hostage deal that includes the withdrawal of Israeli troops from the Philadelphi corridor in Gaza, according to an Israeli official.

Israeli troops remaining in the Philadelphi corridor has been a key sticking point in the ongoing negotiations. Hamas wants a complete withdrawal of Israeli troops from Gaza.

"Everyone who says that it is possible to leave Philadelphi for 42 days, knows very well that it will be for 42 years. The world will not allow us to return," Netanyahu said during Sunday night’s cabinet meeting, according to an Israeli official. "Everyone understands the importance of Philadelphi, and [Hamas leader Yahya] Sinwar understands it best. That is why he insists. All smuggling the weapons to Gaza were through Philadelphi. If we change the cabinet's decision, it will be a terrorist award, you will not return the hostages."

The Hostages Families Forum said in a statement that Netanyahu’s comments are "dangerous." The families said Netanyahu's statement means "there will be no deal, and the families will not get to see their loved ones return home."
