France expelled a Tunisian man on Thursday, the interior ministry said, citing a "severe threat" to public safety as the country remained on high alert a month
after Nice attacks that killed 85 people.
A ministry statement gave no detailed reason for the expulsion of Tunisian national Mohsen M'Hadi, which brought the total number of deportations of this kind to four in August.
A spokesman for the interior ministry was not immediately available for comment. The Socialist government's security record has attracted strong criticism from opposition politicians, less than a year before presidential elections.
Around France, security is tight and several events have been cancelled following a string of attacks over the past two years.
The government has maintained a state of emergency put in place after 130 people were killed in Islamist attacks in Paris in November. At the end of July, attackers interrupted a church service in northern France and slit the priest's throat in an assault claimed by the Islamic State group.
