Tehran , Iran ( CNN ) -- Iran revoked the press cards of Reuters staff in the country after the news agency ran a mistaken headline saying Iran was training female Ninja assassins , Iran 's official news agency reported Tuesday . `` All activities of the Reuters office in Tehran have been temporarily suspended , '' said Mohammad Javad Aghajari , the Culture Ministry foreign media department director general , IRNA said . The controversy stems from a Reuters video showing women clad head to toe in black , running up walls and flipping backwards and diving and rolling over swords held at waist heights . The Culture Ministry official accused Reuters of calling the martial arts students terrorists , when in fact they are `` university students and housewives '' who `` engaged in this sport because of their love for the sport . '' Reuters acknowledged the video report in February `` contained an error '' and that the headline was changed after a complaint . The story 's headline , `` Thousands of female Ninjas train as Iran 's assassins , '' was corrected to read `` Three thousand women Ninjas train in Iran , '' Reuters said in a statement . Eleven Reuters staff members in Tehran were told to hand in their press cards over the incident , Reuters said . `` `` We acknowledge this error occurred and regard it as a very serious matter , '' editor-in-chief Stephen J. Adler said , saying the company `` conducted an internal review and have taken appropriate steps to prevent a recurrence . '' He said Reuters was in talks to restore its journalists ' accreditation . IRNA said authorities would review the case . Iran 's own government-run Press TV ran a similar video story earlier in the year showing even more frenetic martial arts moves , including women leaping onto each other 's shoulders and flipping them over . CNN 's Shirzad Bozorgmehr contributed to this report .
