Israel-Gaza-Lebanon live updates: Israel says it's now striking Iran

Israel Defense Minister Yoav Gallant announced Tuesday that he designated the Al-Qard al-Hassan finance institution -- which Israel alleges is a key financial vehicle for Hezbollah -- a terrorist organization.

"Hezbollah's bank is used to purchase weapons, pay the salaries of terrorists and keep Hezbollah's terror machine going," Gallant wrote in a post on X.

"Degrading Hezbollah's capabilities requires both a military and economic campaign," he added. "We are destroying the terrorist organization's ability to both launch and buy missiles."

Israel has been targeting Al-Qard al-Hassan infrastructure throughout Lebanon in recent days. The strikes have been especially fierce in Beirut, and particularly in its southern Dahiya suburb which is known as a Hezbollah stronghold.

Secretary of State Antony Blinken landed at Ben Gurion Airport in Tel Aviv on Tuesday to begin a tour of Middle East nations in bid to reinvigorate cease-fire talks in both Gaza and Lebanon.

Blinken is expected to meet with Israeli Prime Minister Benjamin Netanyahu on Tuesday.

The revival of stalled cease-fire talks and the prevention of further regional escalation are at the top of the agenda for America's top diplomat.

Blinken's latest regional tour comes just two weeks to go until the U.S. presidential election and with Israel still mulling its retaliation against Iran for the latter's Oct. 1 ballistic missile attack.

The Israel Defense Forces said in a social media post Tuesday that it struck around 230 Hezbollah and Hamas targets in Lebanon and the Gaza Strip over the previous 24 hours.

The strikes killed "dozens" of fighters, the IDF claimed, and hit targets including three purported command centers of a Hezbollah drone unit in southern Lebanon.

In Gaza, fighting continues in the Jabalia area in the north of the strip, which is under intense Israeli bombardment and sweeping evacuation orders.

The IDF said "thousands of civilians have been evacuated" from the area, while "dozens of terrorists were arrested from among the civilians."

Another 10 fighters were killed in a strike in the area, the IDF added. Troops also dismantled several tunnel shafts and a rocket launcher in Beit Lahia, to the north of Jabalia.

Elsewhere, the IDF reported an airstrike on a rocket launcher and ammunition in the southern Rafah area.

The Israel Defense Forces claimed late Hezbollah leader Hassan Nasrallah's gold-filled bunker is located underneath a Beirut hospital, which hospital officials said was being evacuated Monday out of an abundance of caution.

"There are millions of dollars in gold and cash in Hassan Nasrallah's bunker. Where is the bunker located? Directly under Al-Sahel Hospital -- in the heart of Beirut," IDF spokesperson Rear Adm. Daniel Hagari said in a video address Monday.

The IDF released 3D renderings of the hospital building and the bunker it said belonged to Nasrallah, who was killed in Israeli airstrikes in Beirut last month, but has not provided tangible proof. Hagari said the Israeli air force is monitoring the site but added, "We will not strike the hospital itself."

"We are not at war with the people of Lebanon. We are at war with Hezbollah," he said.

Following Hagari's remarks, Lebanese hospital officials said the hospital is being evacuated out of an abundance of caution for the safety of the patients. Lebanese Parliament member Fadi Alameh, the owner of the hospital, said he has requested that the Lebanese army and United Nations Interim Force in Lebanon investigate the Israeli allegations.

Lebanese official Wiam Wahhab said the "talk of weapons depots" at the hospital "is illogical and false."

"This points to the beginning of targeting hospitals, and the army must deploy around the hospital and protect it," he said.

Dr. Youssef Bakhash, the president of the Lebanese Order of Physicians, told the Lebanese media group Al Jadeed that the "pretext of the existence of tunnels and funds beneath Sahel Hospital is aimed at targeting and disrupting the healthcare sector."
