PARIS — The French army just added an unlikely candidate to its list of potential threats: Pokemon Go.

The virtual monsters of the mobile game could lead to intrusions into army bases and even threaten national security, France’s defense ministry said in an internal memo. The military is enforcing a ban on the game, which was developed by Niantic Inc. and mixes augmented reality with digital creatures, to stop staff from unknowingly sharing sensitive data like geographic coordinates or photos.

‘‘Our nation’s defense isn’t a game,’’ said Valerie Lecasble, a spokeswoman for the ministry.

Pokemon Go has been a primary target of the French national police, which has tweeted and posted digital road signs on highways to warn citizens not to play while driving. French Education Minister Najat Vallaud-Belkacem separately said she will ask the game’s makers to delete the most sought-after characters from inside the country’s 63,600 schools.
