CAIRO - US Secretary of Defense Leon Panetta denied media reports on Tuesday that he would discuss possible military attack plans against Iran during a brief visit to Israel.Speaking at a press conference in Cairo shortly before departing for Israel, Panetta said he would be talking about "various contingencies", but said specific military plans would not be put forward."I think it's the wrong characterization to say we are going to be discussing potential attack plans. What we are discussing are various contingencies and how we would respond," he said.Asked whether these included military options, he said: "We obviously continue to work on a number of options in that area, but the discussions that I hope to have with Israel are going to be more about what is the threat that we're confronting and to try to share both information and intelligence on that."
