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 IDF also refused to rule out a possible ground invasion of Lebanon, as it launched a series of extensive air strikes in the country’s southern region.
