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.

The U.S. will soon have the capability to move thousands of American citizens and their families out of Israel by sea, two sources familiar with the planning told ABC News.

Those fleeing by sea will be taken to Cyprus aboard a cruise ship-like vessel set to depart from the northern Israeli port city of Haifa on Monday, the sources said.

Boarding is scheduled to begin at 8 a.m. local time on Monday, according to the U.S. State Department. Boarding will proceed in order of arrival as capacity permits.

Flight departures out of Israel’s Ben Gurion International Airport will also continue "on a rolling basis" on Monday and Tuesday, according to the State Department.

"Please go to Ben Gurion International Airport, Terminal 3, if you wish to depart Israel," the State Department instructed travelers in an advisory on Sunday. "U.S. Embassy personnel will be present to direct you and provide specific flight information. Be prepared to wait."
