Iran's President Mahmoud Ahmadinejad says the Israeli prime minister is a professional assassin, who should be tried for his crimes against the people of Palestine. "[Benjamin] Netanyahu should be tried in court for blockading Gaza and massacring innocent Palestinian women and children," Ahmadinejad said in an interview with CNN's Larry King on Wednesday. "Netanyahu is a professional assassin. All dictators in history accuse others to turn the spotlight away from themselves," the Iranian president said when asked about the Israeli prime minister's worries about Iran. "It is questionable [why] American media feel responsible for this person (Netanyahu)," Ahmadinejad said, adding that "you (American media) are afraid of Netanyahu's warmongering." The Iranian president said the US and Israel's nuclear weapons are the main threat to the world, and they are mistaken to think they can divert attention from this issue by using propaganda campaigns and spreading lies about others. "Iran is firmly after the nuclear disarmament of the US and Israel." Ahmadinejad added that Israel is an "illegitimate regime" and an "occupier" and that the US easily starts wars and massacres people, "they are not qualified to have nuclear weapons and should be disarmed as soon as possible." When asked about the fate of a former FBI agent who allegedly disappeared on Kish Island, the Iranian president said a "joint Iranian-American intelligence committee is to investigate the matter." Robert Levinson, a former FBI agent, disappeared on March 9, 2007 on Kish Island where he was doing investigative work for a private security firm. US officials have dismissed suggestions that Levinson was on assignment for a US government agency. Iranian authorities have announced that Tehran has no information on the matter but they stand ready to work with the FBI if asked by Washington.
