Google is facing legal action from Belgium for not blurring images of military sites.

The Belgian defence ministry had requested that the company obscure air bases in its satellite imagery.

A spokesman for Google said it has been working closely with the Belgian government for two years.

"The Ministry of Defence will sue Google," a spokeswoman for the ministry told Reuters.

Further details about the legal action were not given, although the ministry is said to have requested sites such as nuclear power plants and air bases be blurred on the search giant's satellite imagery.

"It's a shame the Belgium Department of Defence have decided to take this decision," Michiel Sallaets, spokesman for Google in Belgium, said in a statement.

"We have been working closely with them for more than two years, making changes to our maps where asked to make them legal under Belgian law.

"We plan to continue working with them in that spirit of cooperation."

The company has previously been asked to obscure sensitive military sites in countries including France, Germany and the Netherlands.

Google Street View is currently unapproved in India. In 2016 the defence ministry there cited concerns over the security of sensitive military installations as a reason for not letting the company map street-level images.

Earlier this year, security concerns were raised over the fitness tracking firm Strava. The company's "heatmaps", generated by its users as they run or cycle, were shown to expose the exercise routines of military personnel in secret bases around the world.
