While the Israeli government is coming under international pressure to declare a truce, some Israelis want their leaders to take even tougher action against the militants.Residents in towns hit by Hamas rockets have called for a ground invasion. A school in Beersheba was among the latest buildings to be struck. No one was injured, but it illustrated the increased threat posed by long-range missiles fired from Gaza. So far, towns closer to the Strip have been targeted, leaving four people dead. Some of the rockets are homemade, others are factory-produced and smuggled into Gaza. In addition to casualties, their effect is to spread terror across the region. Israeli leaders, including President Shimon Peres, have visited communities which have endured attacks. He said the army was prepared for a land offensive into Gaza.
