An Israeli soldier talks on his mobile phone as he sits on top of an armoured personnel carrier (APC) stationed on Israel's border with the Gaza Strip on November 16, 2012. Israeli officials said the Jewish state was preparing to launch its first ground offensive in four years into the Gaza Strip and the army started calling up reservists.
