Israeli explosion rocks Beirut, crossing another red line for Hezbollah

An Israeli explosion has rocked southern Beirut, crossing another so-called red line for Hezbollah.
The killing of senior commanders and civilians is another major breach of security for the group, with Lebanon already on edge for years. Its foreign minister told an emergency meeting of the UN Security Council that nobody is safe.
With Israel diverting its focus and forces to the north, is it preparing a ground invasion for what it calls the “second phase of the war” on Gaza?
How much of a blow is all this for Hezbollah? And is the region already at war?
