TEL AVIV (AFP) -- Israel must be ready for a "lengthy" military campaign in the Gaza Strip, Prime Minister Benjamin Netanyahu said on Monday.
"We must be prepared for a lengthy campaign" in Gaza, he said in a speech televised shortly after at least four people were killed in southern Israel by a mortar fired by militants in Gaza.
"Israeli citizens cannot live with the threat from rockets and from death tunnels -- death from above and from below," he said.
"We will not end this operation without neutralizing the tunnels whose sole purpose is killing our citizens."
Netanyahu also said that the international community must demand the "demilitarization of Gaza."
