Israel-Gaza-Lebanon updates: Officials say 87 killed in Israeli strikes on Beit Lahia

Over 25% of Lebanon is now under Israeli evacuation orders as Israeli airstrikes continue to increase the number of areas impacted, according to the United Nations refugee agency.

"We have over 25% of the country under a direct Israeli military evacuation order. Just yesterday, we had another 20 villages issued with an evacuation order in the south of the country," Rema Imseis, U.N. High Commissioner for Refugees director for the Middle East, said Tuesday.

"In a country of that size, which is relatively small, and a population that's estimated around 5 million people, you can imagine how dramatic it is that over 1 million people are now without shelter and on the move ... being forced to flee their homes in search of safety," Imseis said.

Hezbollah Deputy Secretary-General Sheikh Naim Qassem said it is "impossible to separate Lebanon's front from Palestine," in a recorded video address released on Tuesday.

There had been speculation over whether Hezbollah would be open to a cease-fire agreement that didn't include Gaza.

Israeli officials have asserted that the aim in Lebanon is to return Israelis home to the north and separate the war in the north from the war in Gaza.

Pentagon Press Secretary Maj. Gen. Pat Ryder said in a statement Tuesday that American troops are already in Israel to support the deployment of a Terminal High-Altitude Area Defense (THAAD) battery to the country.

"An advance team of U.S. military personnel and initial components" required to operate the system arrived in Israel on Monday, Ryder said.

"Over the coming days, additional U.S. military personnel and THAAD battery components will continue to arrive in Israel," he added.

"The battery will be fully operational capable in the near future, but for operations security reasons we will not discuss timelines," Ryder said.
