Vice President Kamala Harris and second gentleman Doug Emhoff marked the first anniversary of the Oct. 7 attack by planting a pomegranate tree -- a symbol of hope and righteousness in Judaism -- at the vice president's residence.

Harris said the tree will "remind future vice presidents of the United States, their families and all who pass through these grounds, not only of the horror of Oct. 7, but the strength and the endurance of the Jewish people."

The vice president underscored her pledge to make sure Israel has what it needs to defend itself.

Harris also said the world must "work to relieve the immense suffering of innocent Palestinians in Gaza who have experienced so much pain and loss over the year."

Emhoff, the first Jewish spouse of a president or a vice president, also spoke about the "incredibly challenging day for Jews."

"We are still hurting, and today feels just as raw as it did one year ago," he said. "What happened on Oct. 7 is seared into our souls."

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.
