Gaza crisis: Israel steps up 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.

The BBC's Wyre Davies described the night's bombings from Gaza.
