An Israeli explosion has rocked southern Beirut, crossing another of Hezbollah's so-called red lines.
The killing of senior officers and civilians is another serious breach of security for the group, which has been in limbo for years. Its foreign minister told an emergency meeting of the UN Security Council that no one is safe.
By shifting its attention and forces northward, is Israel preparing a ground invasion for what it calls the “second phase of the war” in Gaza?
To what extent has all this affected Hezbollah? Is the region already at war?
