The Israeli military hit bank branches across Lebanon overnight to target Hezbollah’s finances, expanding its offensive in an assault that sparked panic as the United States launched a new push for a diplomatic solution to the intensifying regional conflict, NBC News reports. Secretary of State Antony Blinken was set to travel to the Middle East on Monday for a trip that will focus on talks to end the U.S. ally’s conflict with Iran-backed militant groups in Lebanon and Gaza after the killing of Hamas leader Yahya Sinwar — and amid mounting outrage over Israel’s deadly assault on the north of the Palestinian enclave, where the United Nations said life had been made “impossible.” But it also comes as Israel prepares an attack against Iran itself.  An advanced anti-missile system sent by the U.S. was now in place in Israel, Defense Secretary Lloyd Austin said early Monday, boosting its defenses while the U.S. was investigating an apparent leak of top secret documents showing American spy agencies tracking possible Israeli preparations for the strike. Israel targets bank branches across Lebanon Hundreds of residents of Lebanon’s capital and surrounding suburbs were forced to suddenly flee their homes Sunday night after the Israel Defense Forces issued a string of evacuation orders, with blasts ringing out shortly after. IDF spokesman Daniel Hagari warned the evacuation orders for residents of Beirut and other areas of Lebanon were ahead of strikes targeting buildings he said were being “used to finance Hezbollah’s terror activities.” Hagari did not name the institutions being targeted, but over the course of the night a string of branches belonging to the Al-Qard Al-Hassan bank were hit in a volley of airstrikes. The U.S. and Israel have linked the bank to the Iran-backed militant and political group. An NBC News crew in Beirut heard the blasts ring out as Lebanese national media reported strikes on bank branches in the city’s southern suburbs. Video shared on social media and geolocated by NBC News showed buildings on fire and collapsing after apparent air strikes.

In a post on X on Sunday, she said there had only been a “brief window to escape to safety” before “intense blasts” hit. “I can’t describe the panic,” Beirut resident Wafaa Ezeldinne told NBC News after fleeing her home before returning hours later. “Everybody was on the streets. Even displaced people left locations that were close to Al-Qard Al-Hassan. Streets at night were jammed with cars, people.” Ranim Halawani, who works with the Development for People and Nature Association, or DPNA, in the coastal town of Saida, told NBC News that she and others also fled their homes after hearing about the evacuation orders. In the end, she said, “we didn’t have an attack in Saida, but people were afraid and they left.” She said many had since returned to their homes.

Al-Qard Al-Hassan, which translates to “the good loan,” has more than 30 branches across Lebanon, according to local media, with many based in the Shiite-majority southern suburbs of Beirut and at least some appearing to have been connected to residential buildings. Israel’s strikes on the bank marked an expansion of its war against Hezbollah beyond what the IDF has described as the targeting of the group’s military sites. The IDF said Monday that Israeli soldiers also continued to launch ground raids into southern Lebanon and had dismantled “large quantities of Hezbollah’s weapons,” while also killing Hezbollah members, including “tactical-level commanders.” At least 2,464 people, including 127 children, have been killed in Lebanon since hostilities between Israel and Hezbollah began to escalate last year following Hamas’ Oct. 7 terror attack, according to the Lebanese health ministry, while an estimated 1.2 million people have been displaced from their homes. In an interview with Al Arabiya on Monday, Lebanese Prime Minister Najib Mikati said he believed there would be “no solution except through diplomacy” to bring fighting in the region to an end but that he’d had no direct contact with Hezbollah since the middle of last month. Israeli military making life ‘impossible’ in northern Gaza, U.N. says Meanwhile, Israeli forces continued a deadly offensive in northern Gaza, where dozens of people were killed over the weekend in Israeli airstrikes in the areas of Beit Lahia and the nearby Jabalia refugee camp, according to local health officials. The IDF said Monday that troops had killed militants and continued to dismantle militant infrastructure and tunnel shafts in the area of the Jabalia refugee camp over the past day. The military said troops were also operating across southern and central Gaza.

Over the past two weeks, it said, “the Israeli military has taken measures that make life in north Gaza impossible for Palestinians while repeatedly ordering the displacement of the entire governorate.” Zoya Awky reported from Zouk Mosbeh and Chantal Da Silva from London This story first appeared on NBCNews.com. More from NBC News: U.S. investigating apparent leak of ‘top secret’ U.S. documents about Israel What Netanyahu’s threat of Gaza-like destruction signals about Israel’s goals in Lebanon Is Iran’s ‘axis of resistance’ collapsing under Israeli attacks?
