Israel-Gaza-Lebanon updates: Iranian president responds to Israel's retaliatory attacks

U.S. Defense Secretary Lloyd Austin spoke with Israeli Minister of Defense Yoav Gallant Wednesday to discuss Israel's operations in Lebanon and the humanitarian situation in Gaza, the Pentagon said in a statement.

"Secretary Austin welcomed the movement of humanitarian assistance through the Erez crossing and urged the Government of Israel to take all necessary steps to address the dire humanitarian situation in Gaza," Pentagon Press Secretary Maj. Gen. Pat Ryder said of the call.

Austin also asked that Gallant and Israel "seize opportunities for the release of hostages and a ceasefire" following the death of Hamas leader Yahya Sinwar.

Austin also expressed concerns about the reports of Israeli strikes that have struck Lebanese forces and "emphasized the importance of taking all necessary measures to ensure the safety and security of the Lebanese Armed Forces and UNIFIL forces," according to the statement.

The Gaza Civil Defense said its work has "completely stopped" in northern Gaza as "the situation there has become catastrophic," according to a statement released Wednesday.

"Citizens there are now without humanitarian services," the Gaza Civil Defense said.

Medical supplies have also run out at Kamal Adwan Hospital in northern Gaza, the director of field hospitals in Gaza said Wednesday.

Nearly 200,000 people have been displaced across various regions of Lebanon as the number of Israeli strikes on the country approaches 11,000, according to a report from the Lebanese Ministry of Public Health.

The highest concentrations of displaced persons are in Mount Lebanon and Beirut, though the estimated total number of displaced individuals is likely much higher, the ministry said.

At least 2,574 people were killed and 12,001 others were injured since the increase in strikes began, the ministry said.

Since the increase in strikes began, 1,097 centers have been established to accommodate the displaced, with 922 of these centers reaching maximum capacity, the ministry said.

From Sept. 23 to Oct. 23, 344,819 Syrian nationals and 150,104 Lebanese nationals crossed the Lebanese border into Syria, the ministry said.

More than 150 people in northern Gaza's Kamal Adwan Hospital are in critical condition and are facing increasingly dire conditions, according to the hospital director.

Health services cannot be provided to the sick and injured due to the depletion of medical supplies, according to the director.

"Kamal Adwan Hospital remains partially functional but is struggling to meet growing needs due to intensified hostilities in the north and a shortage of medical supplies and fuel. A strike near the hospital causing damages to the gate was reported earlier today, 22 October," the World Health Organization said in a statement Wednesday.

"As hostilities intensify in North Gaza, WHO is deeply concerned about the last two functional hospitals – Kamal Adwan and Al-Awda – which must be protected. A complete lack of health care in North Gaza would make an already catastrophic situation worse, and lead to more lives being lost," the WHO said.
