Ukrainian-Russian man detained in France on terror charges

Authorities in France have detained a Ukrainian-Russian man on terror charges for allegedly trying to make an explosive device in a hotel room.

France has been on high alert in the run-up to the Paris Olympics, which open next month.

French prosecutors say the 26-year-old dual national suffered serious burns from an explosion in a hotel room outside Paris on Monday.

Investigators found materials used to manufacture explosives at the scene.

They detained the man on suspicion of participation in a terrorist conspiracy and a bomb plot.

Some French media outlets report the man is from eastern Ukraine.

They quote investigative sources as saying he was fighting on the Russian side in Russia's invasion of Ukraine.

Last month, French authorities arrested a man from Chechnya in southern Russia on suspicion of plotting a terror attack at an Olympic venue.
