Rumsfeld's remarks:

Q: Mr. Secretary, after the attack in London, today, we had another attack in Israel. Do you believe that any regime in the Middle East, let's say Iran, could be behind or could be supporting these kinds of terrorist attacks?

SEC. RUMSFELD: As I say, with respect to the attacks in the U.K., I'm inclined to let the investigations proceed, and whatever conclusions are reached will be reached.

With respect to attacks in Israel, we know that Iran has been on the terrorist list. We know that Iran has been assisting Hezbollah and other organizations and moving equipment and people down through Damascus into Beirut and down into positions where they can attack Israel for years and years and years and years. I wouldn't want to suggest that I know about the attack today, but clearly that's been one of the stated and continuous purposes of Iran, is to harm Israel.
