There have been no official statements by the Iranian authorities about the attack but a commentary on state TV’s website called the claims by Mr Netanyahu and others “ridiculous” and “sensational”. The website described the Israeli charges as attempts to discredit Iran and allies such as Syria.
Israeli security chiefs met late last night and officials said any reaction would probably be a limited operation, most likely under the auspices of the Mossad spy agency. The sources said officials were also reviewing security at potential Israeli targets, such as airports and diplomatic installations.
Iran has blamed Israel for a series of covert attacks on Iranian nuclear targets, ranging from the assassination of nuclear scientists to computer viruses that have damaged centrifuges.
