The head of the Shin Bet security service, Yoram Cohen, said that Iran is trying to strike Israeli targets around the world in a bid to stop the assassinations of its nuclear scientists. Cohen said that it did not matter whether or not Israel in fact took out the nuclear scientists, but that a serious country like Iran could not let this go on. They want to deter Israel and extract a price so that decision makers in Israel think twice before they order an attack on an Iranian scientist. He added that Iran was working very hard abroad through the Iranian Revolutionary Guards to hit Israeli targets.
