The U.S. State Department has said it believes the Rafah crossing, which is located on the border of Gaza and Egypt, will be open on Monday morning.

Quoting media reports, the State Department said the crossing will open at 9 a.m. local time.

"We anticipate that the situation at the Rafah crossing will remain fluid and unpredictable and it is unclear whether, or for how long, travelers will be permitted to transit the crossing," the State Department wrote in a post on X (formerly Twitter). "If you assess it to be safe, you may wish to move closer to the Rafah border crossing – there may be very little notice if the crossing opens and it may only open for a limited time."

Israel Defense Forces attacked “military infrastructure” that belongs to “the terrorist organization Hezbollah” in Lebanon, the IDF said in a post on X (formerly known as Twitter) early Monday morning local time.

“IDF forces attacked the military infrastructure of the terrorist organization Hezbollah in Lebanon a short time ago; this was in response to the shooting that was carried out yesterday at Israeli territory,” the post read.

The IDF did not share details on when the attacks occurred.

Israeli forces have been engaging in skirmishes with the Lebanese militant group along Israel's northern border with Lebanon in the days since Hamas' surprise attack on Israel from Gaza on Oct. 7.

An agreement has been reached to open the border crossing out of Rafah, in southern Gaza, on Monday for the entry of foreigners and dual nationals into Egypt as well as the delivery of humanitarian aid into Gaza, a security source told ABC News.

The Rafah border crossing is the sole crossing point between Egypt and the Gaza Strip. The crossing will be opened for a few hours on Monday and then closed again in the late afternoon, the source said. The exact times of the opening and closing were not specified.

Israel will deploy crews from the Red Cross to inspect aid shipments flowing into the Palestinian side through the border, the source added.

Military forces in the North Sinai cities of Al-Arish and Sheikh Ziweid moved closer to the border late on Sunday in preparation for the opening, the source said.

Fourteen staff members from the United Nations Agency for Palestine Refugees have been killed in airstrikes on the Gaza Strip, United Nations Relief and Works Agency Commissioner-General Philippe Lazzarini said during remarks from the UNRWA headquarters in Jerusalem on Sunday.

Most of the UNRWA's 13,000 staff members in the Gaza Strip have now been displaced or are "out of their homes," Lazzarini added.

Unless supplies are brought into Gaza, UNRWA and other international aid workers will not be able to continue humanitarian operations, Lazzarini said.

"As I speak with you, Gaza is running out of water and electricity," Lazzarini said.

At least 400,000 people who have been displaced in Gaza are currently sheltering in UNRWA schools and buildings, most of which have not been equipped as emergency shelters, Lazzarini said.
