DUBAI (Reuters) -Israel will receive a "devastating and decisive response" if it attacks Iran, Tehran's Revolutionary Guards said on Thursday, days after CNN reported U.S. intelligence suggesting Israel was making preparations to strike Iranian nuclear facilities.

Iran’s top diplomat warned Thursday that his country would take “special measures" to defend its nuclear facilities if Israel continues to threaten them, raising the stakes further ahead of a new round of talks with the United States.

Iran warned it would take action against Israel and hold the US “legally responsible” if the Jewish state acts on reported plans to attack the Islamic Republic’s nuclear facilities.
