Israel and Hezbollah accelerated their cross-border attacks overnight into Sunday with their leaders exchanging saber-rattling threats in a rapidly deteriorating situation that has the adversaries as close to full-out war as they have been in their nearly yearlong conflict.

A leader of the Iranian-backed militia said its latest barrage was “just the beginning,” and an Israeli military official said, “Our strikes will intensify.”

Hezbollah has fired projectiles targeting areas farther into Israeli territory than the majority previous strikes on Sunday, with the last 48 hours bringing the most intense exchanges of fire between Israel and the Lebanese militant group since October 7.
