US vows to send thousands more troops and aircraft as Israel invades Lebanon

The additional personnel includes squadrons of F-15E, F-16, and F-22 fighter jets and A-10 attack aircraft, and the personnel needed to support them.

The jets were supposed to rotate in and replace the squadrons already there. Instead, both the existing and new squadrons will remain in place to double the airpower on hand.

Singh linked the additional deployments directly to rhetoric from senior Iranian officials, including Ayatollah Ali Khamenei, who has called for all Muslims to stand with Hezbollah as it confronts Israel.

US Secretary of Defense Lloyd Austin spoke with Israeli Defense Minister Yoav Gallant on Monday, the Department of Defense said.

"They agreed on the necessity of dismantling attack infrastructure along the border to ensure that Lebanese Hezbollah cannot conduct October 7-style attacks on Israel's northern communities," the department said in a statement.

Austin reaffirmed that a diplomatic resolution is required to ensure that civilians can return safely to their homes on both sides of the border, according to the department.

Israel's operations in Lebanon follows its deadly detonation of booby-trapped Hezbollah pagers, two weeks of airstrikes, and its killing on Friday of leader Hassan Nasrallah in Beirut.

The intensive air strikes have eliminated several Hezbollah commanders but also killed about 1,000 civilians and forced one million to flee their homes, according to the Lebanese government.

Overnight, strikes hit Beirut's southern suburbs, a security source said. A Reuters reporter witnessed a flash of light and a series of loud blasts about an hour after the Israeli military warned residents to evacuate areas near buildings it said contained Hezbollah infrastructure south of the capital.

In the past 24 hours, at least 95 people had been killed and 172 wounded in Israeli strikes on Lebanon's southern regions, the eastern Bekaa Valley, and Beirut, Lebanon's health ministry said early on Tuesday. Hezbollah's deputy leader Naim Qassem on Monday said "the resistance forces are ready for a ground engagement" adding that Hezbollah continued to fire rockets as deep as 150 km (93 miles) into Israeli territory.

Lebanon's army has historically stayed on the sidelines of major conflicts with Israel, and in the last year of hostilities has not fired on the Israeli military.

The operation into Lebanon represents an escalation of the conflict in the Middle East between Israel and Iran-backed militants that now threatens to suck in the U.S. and Iran.

Local residents in the Lebanese border town of Aita al-Shaab reported heavy shelling and the sound of helicopters and drones overhead. Flares were repeatedly launched over the Lebanese border town of Rmeish, lighting up the night sky.
