And then there are the salvos exchanged daily with Iran-backed militants across the border in Syria and Lebanon. Our correspondent in southern Lebanon earlier reported on sustained gunfire across the border. How far will it escalate?
Will this conflict draw in the superpowers? For the past two years, the focus has been on the US-Russia showdown over Ukraine. Could Washington and its allies instead find themselves in direct confrontation with Moscow ally Tehran?
