Ukraine’s SBU security agency has said that a Frenchman detained last month with a large cache of arms was planning mass attacks on Euro 2016.
The man, identified by French media as Gregoire M, 25, was arrested on the Ukrainian border with Poland.
SBU chief Vasyl Hrytsak said the man had been planning 15 attacks and was driven by ultra-nationalist views. He had amassed guns, detonators and 125kg of TNT, he said.
Euro 2016 begins in France on Friday.
