Israel launched a ground offensive into Gaza after nightfall Saturday. Defense officials have said about 10,000 soldiers have been massed along the border in recent days.
Hamas says it broadcast a message in Hebrew on Israeli military radio frequencies promising to kill and kidnap Israeli soldiers. The message warned troops they would ``suffer mental illness from the horrors'' its fighters would show them.
Hamas has long prepared for an Israeli invasion, digging tunnels and rigging some areas with explosives. Before moving the ground forces moved in, Israeli artillery shelled border areas, apparently to detonate hidden explosives and mines.
