MNA � Secretary of the Supreme National Security Council Rear Admiral Ali Shamkhani has reacted to the US� announcement of holding an anti-Iran conference in Polish capital Warsaw next month.

�When someone who says �sanctions with maximum pressure� is reduced to holding �seminars and conferences�, it only means that he has lost the upper hand,� Secretary of the Supreme National Security Council Rear Admiral Ali Shamkhani told reporters on Saturday.

His remark was in reaction to a recent announcement by Washington about the holding of an anti-Iran conference in Polish capital Warsaw next month.

Iranian Foreign Minister Mohammad Javad Zarif also reacted to the news, writing in a tweet that the conference is a �desperate circus�, reminding the host and participants that �those who attended last US anti-Iran show are either dead, disgraced, or marginalized. And Iran is stronger than ever.�
