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 neutralising the tunnels whose sole purpose is killing our citizens."
