MISSILES and shells pounded Gaza every minute in a brutal blitz as Israel launched a massive assault to try and flush out terror group Hamas. And last night the brutal siege reached new heights as Israel launched a ground invasion in all but name. Missiles are striking Gaza every minute with no sign of a let up since Israel said last night that “ground forces are expanding their operations”. On the edge of Beit Hanoun, the northern Gaza city closest to Israel, a series of devastated buildings could be seen. Massive airstrikes targeted the Jabalia refugee camp in north-east Gaza as Israeli ground troops penetrated deep into the Gaza Strip.
