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.

Israel and the Hezbollah militant group exchanged heavy fire across the Lebanese border on Sunday, fueling fears of a wider conflict in the region.
