AMMAN, Jordan — Iranian Supreme Leader Ali Khamenei has denied Iran was involved in Hamas' attack against Israel over the weekend. But in televised comments Tuesday, he said: "We kiss the hands of those who planned the attack on the Zionist regime."

Western and Middle Eastern intelligence officials have accused Iran of providing training, money and other assistance to Palestinian militants in the Gaza Strip, who carried out an unprecedented, multifront assault on Israel on Saturday.
