How far will it escalate? Region on edge as Israel ramps up response to Hamas

As Israel mobilises and seals off the Gaza Strip, will it be the prelude to an incursion, an invasion, an occupation? For civilians on the Palestinian side, the nightmare is only at its beginning. 

And then there are the salvos exchanged 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 it all 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?
