Ukraine's intelligence agency SBU says it has thwarted a plot to attack soccer's European Championships in France.

The SBU said in a statement on Monday that it had followed a French man since December and allowed him to purchase five machine guns, two rocket propelled grenades and other weapons before he was arrested on the Ukrainian-Polish border last month.

The SBU didn't identify the man but said he was driven by ultra-nationalist views and planned 15 attacks on bridges, railways and other pieces of infrastructure for Euro 2016 that will be held in France.
