Outgoing President Shimon Peres said in an interview Wednesday with CNN's Becky Anderson that he believed an IDF ground offensive in Gaza "may happen quite soon" unless Hamas stops firing rockets at Israel.

"If they won't stop their missiles, there will be a ground attack," he said. "That is the logical conclusion."

"We didn't start the war today. They started it already several days ago, and they continued, and they spread their fire on more areas in Israel." Peres said. "It may happen quite soon... If they continue, sooner or later, this will be the response." 

While Peres was speaking on his own and his position may not outline an official government policy, Israeli Intelligence Minister Yuval Steinitz earlier told CNN that a ground operation "might become necessary."
