Israel Approaching Land Invasion of Gaza

Looks like it on the ground

Israel seemed to be preparing to step up its military operation against Hamas militants in the Gaza Strip on Friday, as air raid sirens wailed in Jerusalem and Tel Aviv and media reported another rocket had fallen near the Tel Aviv.

CBS News correspondent Allen Pizzey and his team were forced by the Israeli military -- along with other news crews -- to move away from the border with the Gaza Strip on Friday morning, another signal pointing to a possible ground incursion into the tiny Palestinian territory.
