They are suspected of being involved in a hostage-taking.
France confirmed on Tuesday the arrest of French nationals in Mali, while Bamako mentioned the arrest of four people, members according to the junta "of a group of criminals and drug traffickers".
“We have been informed of the arrest of French nationals in Mali.
We are monitoring the situation in conjunction with the French Embassy in Bamako,” said the Ministry of Foreign Affairs.
The Quai d'Orsay did not provide any other details, in particular on the exact number of people concerned.
On Monday, the Malian Ministry of Security and Civil Protection mentioned in a press release "an operation by the security forces" on Sunday "to free hostages and apprehend the members of a group of criminals and drug traffickers who were holding them" in Missabougou, in the east of the Malian capital.
Accused of being responsible for taking hostages
Ten hostages including three women and three children were released and "four criminals, including a Franco-Senegalese, two French and a Franco-Malian" were arrested, the statement said.
Bamako claims that the hostages had been held since November 18 and that the group was demanding 900 million CFA (1.37 million euros), or failing that, information to locate a stock of cocaine recently seized by Malian customs.

The last French soldier left the country in August, after nine years of combat against the jihadists alongside the Malian army.
The junta's colonels have now turned, militarily and diplomatically, to Moscow.
