Foreign Ministry Spokesman Bahram Qassemi released a statement on Friday, expressing deep regret for the incident.
As we have mentioned several times, terrorism is an ominous phenomenon that will be eradicated only with international cooperation and consensus, he stressed.
Qassemi underlined that any negligence or double standards on battling terrorism is condemned and will be doomed to failure.
A French-Tunisian criminal well known to the police for armed attack mowed down people when he drove a heavy truck at high speed into a crowd that had watched Bastille Day fireworks in the French Riviera city of Nice late on Thursday.
French President Francois Hollande says the death toll has risen to 90.
Local officials say the truck was on the sidewalk for more than a mile before police killed the driver.
At least 120 people have been injured in the deadly incident.
