DUBAI/PARIS, July 22 (Reuters) - An Iranian foreign ministry official denied on Wednesday that two French diplomats were mistreated by Iranian security personnel who detained them for several hours in Tehran.

Paris swiftly dismissed the Iranian official's comments, which were reported by state media, and has warned that there will be consequences over the incident.

The French foreign ministry summoned the Iranian charge d'affaires on Tuesday over the incident, in which it said two French embassy staff had been detained and physically intimidated by Iranian security services.
