Iranian President Mahmoud Ahmadinejad called his French counterpart, Nicolas Sarkozy, "young and inexperienced" in an acrimonious and threatening letter, the daily newspaper Le Monde reported Friday. Sarkozy's spokesman, David Martinon, confirmed the French president received a letter from Ahmadinejad on Monday. But Martinon said he had not read the letter and could not confirm Le Monde's description of its contents. The spokesman said, however, that he had been told that the note "adds nothing to the position already expressed many times by the Iranian authorities." In his six months as president, Sarkozy has toughened France's stance on the issue, pushing for more sanctions against Teheran and warning of the risk of war if diplomacy fails.
