Iran has launched a missile attack on Israel - the Israeli military says around 180 missiles were fired, most of which were intercepted.
No serious injuries have been reported so far and Israeli authorities say civilians can leave bomb shelters.
Israeli Prime Minister Benjamin Netanyahu says Iran "made a big mistake tonight, and will pay for it."
Israeli troops have invaded Lebanon, in what the Israeli military calls a "limited, localised and targeted" ground operation against Hezbollah.
On Tuesday morning, an Israeli security official told the BBC there had been "no clashes" yet - but a military spokesman later told people in around 25 Lebanese villages to evacuate.
The UN and EU have reiterated calls for a ceasefire, with the UN Security Council due to meet tomorrow.
