Israel-Gaza-Lebanon updates: Netanyahu calls UN troops Hezbollah 'human shields'

Israeli incursions into Lebanon continue to be limited, State Department spokesperson Matthew Miller said Monday, noting that this assessment does not "offer any kind of forecast about what's going to happen."

Miller asserted that U.S. officials were still engaged in talks about "what the path forward ought to look like" with a variety of partners in the Middle East.

"Just because we don't make the details of those conversations public, which we are not at this point, doesn't mean that we are not actively engaged in them," he said.

Similarly, he said Israel's campaign in Lebanon hadn't impacted the administration’s drive to secure a cease-fire in Gaza and characterized Hamas as the main hurdle that has been "unwilling to engage in a meaningful way with the mediators.”

The State Department said Monday it organized a flight to carry Americans out of Lebanon on Monday.

The flight carried approximately 150 American citizens, legal permanent residents and their family members from Beirut to Istanbul, the State Department said.

The department said earlier Monday that it had also organized two flights over the weekend carrying a combined 235 passengers from Beirut to Istanbul.

Monday's flight brings the total number of U.S. charter flights from Lebanon over the past week to eight, with 900 combined passengers, according to the State Department.

The State Department said it has additionally blocked off 868 seats for Americans on commercial flights, with a significant share of them filled.

Officials from the U.S. Embassy in Beirut are now in contact with approximately 8,500 people inside Lebanon who have asked for more information about departing the country.

State Department spokesperson Matthew Miller said Monday that does not mean that all intend to leave, though the department has assessed that there is still significant demand for additional government charter flights among Americans in Lebanon.

In a warning to vacationers, beachgoers and boaters, the Israel Defense Forces said they will soon operate against "Hezbollah maritime targets" south of the Awali River line.

President Joe Biden and first lady Jill Biden joined a memorial candle lighting held Monday in the Blue Room of the White House in remembrance of the victims of the Oct. 7 attack.

Rabbi Aaron Alexander recited in Hebrew "El Malei Rachamim" ("God Full of Mercy"), a traditional Jewish prayer for those who have died, then recited it in English.

Biden then lit the yahrzeit candle before observing a moment of silence. Biden made the sign of the cross after a few moments.

Alexander is a family friend of the Goldberg-Polin family. American-Israeli Hersh Goldberg-Polin, 23, was taken hostage by Hamas on Oct. 7 at the Nova Music Festival. His body was recovered by Israeli forces in late August.

Biden also spoke with Israeli President Isaac Herzog earlier Monday to express his "deepest condolences" to Israelis and families of the Oct. 7 attack, the White House said.
