They may not have their hands on nuclear weapons yet, but Iran is already at war with Israel - on the internet at least.

Hackers have made repeated efforts to block a message posted by senior American-Jewish figure Malcolm Hoenlein.

In it, Hoenlein tells the people of Iran: "We want to work with you. It is regrettable that you have a leadership that does not care about your welfare."

As a result, there have been dozens of attempts to hack into the site, and the hackers have succeeded in having the website designated "dangerous" on the Google search engine.

Perhaps that is what the Iranian rocket scientists do in their spare time.
