From the small Israeli town of Metula right on the border with Lebanon, BBC reporter Jon Donnison heard what sounded like a full-on gun battle just a kilometre (0.6 miles) or so away.
For 10 minutes heavy bursts of machine gun fire echoed across the valley, interspersed with what sounded like artillery fire. The Israeli army says it is trying to push Hezbollah fighters – supported by Iran – back from the south of Lebanon.
