(NEW YORK) — Israel and Hezbollah are exchanging hundreds of cross-border strikes in the wake of the shocking explosions of wireless devices across Lebanon last week.

Here’s how the news is developing:

IDF, Hezbollah begin new day of cross-border fire

The Israel Defense Forces said Tuesday its warplanes struck “dozens of Hezbollah targets in southern Lebanon,” with artillery and tanks also conducting fire missions in the area.

Hezbollah, meanwhile, fired at least 125 rockets overnight into Tuesday morning. Sirens were sounding through the early morning in northern Israel.

At least nine people suffered minor injuries as a result of rockets fired into the Western Galilee region of northern Israel on Tuesday morning, according to Israel’s Magen David Adom emergency service.

At least 492 people were killed in Lebanon by Israeli strikes on Monday, according to Lebanese authorities. At least 1,645 people were reported injured.

The IDF said it struck at least 1,600 targets in Lebanon over the past 24 hours.

Blinken seeks ‘off ramp’ as Israel pounds Lebanon, official says

A senior official in President Joe Biden’s administration told ABC News the U.S. cannot rule out the possibility of an Israeli invasion into Lebanon following the escalation of its airstrike campaign on Monday.

“I think it is important for everyone to take Israeli preparations seriously,” the senior administration official said.

The U.S. is putting its hope in engagements on the sideline of the United Nations General Assembly this week, said the senior administration official, who expressed hope that the informal meetings could lead to “illusive solutions” or “at least make some progress” toward resolving the crisis in the Middle East.

The official said Secretary of State Antony Blinken would discuss “the increasing challenges” across the so-called “Blue Line” dividing Israel and Lebanon at a meeting with his G7 counterparts.

At that engagement and through the week, the a key U.S. focus will be “finding an off ramp,” they said.

“We’ve got some concrete ideas with allies and partners we are going to be discussing,” the official added.

New details emerge over US troops being sent to Middle East

Lebanon warns UN its citizens face ‘serious danger’ amid Israel-Hezbollah conflict

A Lebanese parliament member addressed the United Nations General Assembly Monday sharing a warning that the country’s citizens are in danger as tensions between Israeli forces and Hezbollah intensify.

Member Bahia El Hariri attended the U.N. meeting in place of Lebanon’s Prime Minister Najib Mikati.

“The people of Lebanon are in serious danger after the destruction of large areas of agricultural land and the targeting of residential buildings in the majority of the regions of Lebanon,” Hariri said.

“This has damaged the economy of our country and threatened our social order, especially since several countries have asked their nationals to leave our country,” she added.

Separately, U.N. Secretary-General António Guterres said he was “gravely alarmed” by the escalating situation between northern Israel and southern Lebanon and the “large number of civilian casualties, including children and women, being reported by Lebanese authorities, as well as thousands of displaced persons, amidst the most intense Israeli bombing campaign since last October,” in a statement issued by his spokesperson Monday.

“The Secretary-General is also gravely alarmed” by the continued Hezbollah strikes on Israel, the statement added.
