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

The Pentagon released a readout Wednesday evening following a phone call between Secretary of Defense Lloyd J. Austin and Israeli Minister of Defense Yoav Gallant.

The two discussed "Israel’s operations in Lebanon and broader regional security matters," according to the readout.

"Secretary Austin and Minister Gallant discussed the deployment of a Terminal High-Altitude Area Defense (THAAD) battery as an operational example of the United States’ ironclad support to the defense of Israel. The Secretary encouraged the Government of Israel to continue taking steps to address the dire humanitarian situation, noting the recent action by Israel to increase the amount of humanitarian assistance entering Gaza," the Pentagon said in a statement.

Austin also "raised the need to pursue a diplomatic pathway to provide security for civilians on both sides of the Israel-Lebanon border as soon as feasible," the Pentagon said.

The Israel Defense Forces said an incident of an Israeli tank firing at a UNIFIL position in southern Lebanon is "under examination" when asked by ABC News.

"The Hezbollah terrorist organization has been devising and taking forward attacks against the State of Israel and IDF soldiers from terror infrastructure sites that have been built within and adjacent to UNIFIL posts for many years," the IDF said in a statement when asked about the incident.

This is the first time the IDF has said Hezbollah infrastructure has been built "within and adjacent" to UNIFIL posts. In the same statement, the IDF said UNIFIL "infrastructure sites and forces are not a target."

Israel's attacks on UNIFIL sites in southern Lebanon have been widely condemned by the international community.

Israel is planning to respond after Iran attacked Israel with more than 200 missiles on Oct. 1.

The source would not give more details on specific targets and would not comment on whether they are strictly Iranian military targets.

No timeline has been given for the strikes to be carried out.

"If the cholera outbreak ... spreads to the new displaced people, it might spread very fast," Abdinasir Abubakar, the WHO representative in Lebanon, said in a press conference.
