The Israeli military was preparing to expand strikes across Lebanon early on Monday, as the long-simmering conflict with Hezbollah threatened to explode into larger war.

The Israeli military on Monday warned civilians in southern Lebanon to move away from Hezbollah position and said it was intensifying attacks on its neighbor as the region lurched closer to an all-out war.

The Israeli military said on Monday it was conducting extensive strikes against targets of the Iranian-backed Hezbollah movement in Lebanon, which come amid some of the heaviest cross-border exchanges of fire in nearly a year of conflict.
