US fears Middle East conflict growing as Israel and Hezbollah exchange attacks as Gaza ceasefire deal teeters

US officials are publicly and privately urging their Israeli allies to avoid escalating the back-and-forth strikes that have been taking place for months between the IDF and the Lebanese militant movement Hezbollah, arguing the fighting could turn an already deadly two-party war in Gaza into an even worse regional conflict.

"We are concerned about an increase in activity in the north. We don’t want this to escalate to a broad regional conflict and we urge de-escalation,"  Pentagon deputy spokeswoman Sabrina Singh told reporters on Wednesday.

On Tuesday, Israeli forces killed a senior Hezbollah commander, Taleb Sami Abdullah, known as Abu Taleb, near the Lebanon-Israel border. The strike prompted the Iran-backed militia and political movement to fire over 200 missiles into Israel today in response, its largest attack since the October 7 conflict between Israel and Hamas began.

“Our response after the martyrdom of Abu Taleb will be to intensify our operations in severity, strength, quantity and quality,” senior Hezbollah official Hachem Saffieddine said during a funeral for the slain militant on Wednesday. “Let the enemy wait for us in the battlefield.”

Israel, in turn, reportedly conducted heavy bombing raids in southern Lebanon on Wednesday.

Tensions have been ratcheting up this month. A series of Hezbollah attacks last week set off massive forest fires in Northern Israel, and Israeli prime minister Benjamin Netanyahu promised “a very strong action” in response.

US Secretary of State Antony Blinken, speaking on Wednesday from Qatar, one of the nations brokering negotiations between Israel and Hamas, argued that a ceasefire between the two sides would help calm the tension between Israel and Lebanon as well.

“Now, there’s no doubt in my mind that the best way to empower a diplomatic solution to the north, Lebanon, is a resolution of the conflict in Gaza and getting the ceasefire,” he told reporters. “That will take a tremendous amount of pressure out of the system.”

There’s still considerable daylight between Israel, Hamas, and the US, over a proposed ceasefire deal.

The US has publicized a ceasefire plan, which it says Israel backs, which would begin with a six-week ceasefire and hostages-for-prisoners swap, then be followed by a three-stage rebuilding process in Gaza and further negotiations towards a political settlement.

Israeli prime minister Benjamin Netanyahu, however, has yet to publically endorse the plan, and is under considerable domestic pressure from his right-wing coalitition to fully destroy Hamas before accepting any ceasefire.

The Palestinian group submitted its response to negotiators late Tuesday. Senior Hamas official Osama Hamdan told AFP it is seeking to add provisions guaranteeing "a permanent cease-fire and complete withdrawal" by the IDF, demands Israel has rejected.
