White House national security adviser Jake Sullivan and Israeli Minister of Strategic Affairs Ron Dermer held a virtual meeting Wednesday to discuss the ongoing tensions at the Israel-Lebanon border, according to a US official familiar with the matter.

The official, who was not authorized to comment publicly, said that senior White House national security officials Brett McGurk and Amos Hochstein also took part in the discussions about concerns that the tensions with the Lebanese militant group Hezbollah could cause the war in Gaza to spread into a regional conflict.

White House national security spokesperson John Kirby said White House officials on Wednesday continued conversations with Israeli officials in hopes of sealing a cease-fire deal.

US officials also spoke with Egyptian and Qatari officials, who have served as intermediaries for Hamas. But Kirby declined to confirm that Sullivan and other senior White House officials spoke with Dermer on Wednesday.
