Over 1,000 people in Lebanon have been killed in the last two weeks.
Israel's Lebanon operation continues as leaders consider their response to Iran's long-range attack on Tuesday, in which hundreds of missiles were fired into the country, according to Danny Danon, Israel's ambassador to the United Nations.
Iran said the unprecedented attack was retaliation for a wave of assassinations carried out by Israel over the last several weeks targeting Hezbollah, including leader Hassan Nasrallah.
Most of the missiles were intercepted, but "several hits were identified, and the damage is being assessed," an Israeli security official said.

Those injured are being taken to Poria Hospital in Tiberias and Rambam Hospital in Haifa, according to officials.
Debris and shrapnel have been reported in two primary areas, officials said.
Some buildings and properties have sustained damage, and medical sources indicate that there are several reports of minor injuries.
The Israel Defense Forces ordered further evacuations in Beirut as its strikes continue to hit the city.
Residents of the southern suburb of Burj al-Barajneh and Hadath Beirut were urged to evacuate, according to the IDF.
"For your safety and the safety of your family members, you must evacuate this building and the buildings adjacent to it immediately and stay away from it for a distance of no less than 500 meters," the IDF said in an urgent message Sunday.

As the conflict between Israel and Hezbollah continues, the Lebanese prime minister's office said the total death toll now stands at 2,036 people killed, since the beginning of the conflict on Oct. 8.
On Saturday, 23 people were killed and 93 wounded across both the south, north and other regions of Lebanon, including Bekaa, Baalbek-Hermel and Mount Lebanon, according to the Lebanese Ministry of Health.
The governor of the Lebanese region of Baalbek-Hermel said Sunday that an Israeli strike hit within 500-700 meters of ancient Roman ruins in the area. The Roman temples in Baalbek are UNESCO World Heritage sites and date back to the second century, according to UNESCO.
The U.N. peacekeeping mission in Lebanon known as UNIFIL, which staffs dozens of posts in southern Lebanon and along the Israeli border, said in a statement Sunday it is "deeply concerned" by recent IDF activity near one of its bases, 6-52, which is manned by Irish peacekeepers.
UNIFIL and the Irish government have both said the IDF requested the troops leave the post, and that both the UN and the Irish government rejected the requests.
UNIFIL released a statement, saying, "This is an extremely dangerous development. It is unacceptable to compromise the safety of U.N. peacekeepers carrying out their Security Council-mandated tasks."
After not issuing any evacuation orders for south Lebanon on Saturday, the IDF issued a new order on Sunday, listing some 25 towns, including 10 new towns and villages added to the list, for a total of 98 towns and villages in southern Lebanon now having been asked to evacuate, according to the IDF.
