Israel has called up some 75,000 reservists in preparation for a potential ground war in Gaza against the terrorist group, Hamas. For the past several days, some 450 rockets have been launched by Hamas against Israel, including some Iranian-built, long-ranged rockets capable of hitting Tel Aviv and Jerusalem. Egypt has now entered the game as well, with the Muslim Brotherhood government vowing to support Hamas. Several rockets fired Friday night into Israel came from Egyptian-held territory in the Sinai Peninsula. So far, Israel has been dishing out counterstrikes as quickly as possible, targeting rocket launching sites which are usually located in urban areas. Their ′Iron Dome′ rocket-defense missiles have stopped about 100 Hamas-fired rockets, leading Israel to deploy additional batteries of Iron Dome during this heightened state of emergency.
