The man, who is currently being held by Ukrainian authorities pending a possible extradition request from Paris, was planning an attack in France, M6 reported.

A Frenchman reported to be carrying weapons and explosives for a planned attack in France was arrested on the Ukrainian-Polish border in late May, the Ukrainian Border Guard said on Saturday.

French broadcaster M6 reported on Friday that the 25-year-old was arrested by Ukrainian border guards with an arsenal of weapons and explosives including rocket launchers and Kalashnikov assault rifles in his vehicle.

A spokesman for the Ukrainian Border Guard, Oleg Slobodyan, confirmed the arrest. A spokeswoman for Ukraine’s SBU security service declined to comment.

The French interior ministry said the case is being handled by judicial officials. The Polish border guard declined to comment.

Security officials in Europe are on high alert after gunmen killed 130 in Paris in November last year and suicide bombers blew themselves up at Brussels airport and on the metro in March, killing 32.

The United States on Tuesday warned its citizens of possible further attacks in Europe, saying targets could include the UEFA Euro 2106 soccer championship in France beginning next week.
