Tehran (IP) - Iran's Foreign Minister strongly condemned Thursday's knife attack on people in France's Nice.

Iran PressIran News: In a tweet on Thursday, Mohammad Javad Zarif referred to the escalating vicious cycle of hate speech, provocations, and violence and stressed that it must be replaced by reason and sanity. 

"We should recognize that radicalism only breeds more radicalism, and peace cannot be achieved with ugly provocations," Zarif emphasized.

An attacker with a knife killed two people and wounded several others at a church in the French city of Nice on Thursday. The city's mayor described it as terrorism.

The attack comes while France is still reeling from the beheading earlier this month of French middle school teacher Samuel Paty by a Chechen origin man.

It was not immediately clear what the motive was for the Nice attack.

London of Britain also is a city regularly witnessing cases of stabbing.
