Speaking shortly before senior diplomats from six world powers were scheduled to meet in Paris on Tuesday to discuss sanctions against Iran over its nuclear programme, Iranian president Mahmoud Ahmadinejad warned the European Union that any punitive measure would be considered an act of hostility by Tehran. "I am telling you in plain language that from now on, if you try, whether in your propaganda or at international organisations, to take steps against the rights of the Iranian nation, the Iranian nation will consider it an act of hostility," Ahmadinejad said.
