Gaza crisis: Israel intensifies aerial attack
Israel's aerial bombardment of Gaza has intensified after it authorised the call-up of 30,000 army reservists, amid reports of a possible ground offensive.
Israel said it fired at more than 130 targets in Gaza overnight, saying militants fired 11 rockets from Gaza.
On Thursday rockets were fired 70km (45 miles) north of Gaza towards Tel Aviv.
Fighting has intensified since Israel killed Ahmed Jabari, the military leader of the Islamist group that controls the territory, on Wednesday.
