KIEV - Ukraine's state security service said on Monday a French citizen detained in late May on the Ukrainian-Polish border had been planning attacks in France to coincide with the Euro 2016 soccer championship it is hosting.
On Saturday the Ukrainian border guard service reported the unnamed 25-year-old had been arrested with an arsenal of weapons and explosives including rocket launchers and Kalashnikov assault rifles in his vehicle.
SBU chief Vasily Gritsak said the man had made contact with armed groups in Ukraine with the aim of buying weapons and explosives.
His intended targets included Jewish and Muslim places of worship and buildings involved with the soccer tournament, Gritsak said. French government administration buildings, including those dealing with tax collection, were also a target.
"The Frenchman spoke negatively about his government's actions, mass immigration, the spread of Islam and globalization, and also talked about plans to carry out several terrorist attacks," Gritsak told journalists.
"The SBU was able to prevent a series of 15 acts of terror (planned) for the eve and during the Euro soccer championship," he said.
Security officials in Europe are on high alert after Islamist militants killed 130 people in Paris last November and suicide bombers killed 32 people at Belgium's main international airport and on the Brussels metro in March.
The United States has warned its citizens of possible further attacks in Europe, saying targets could include Euro 2016 which opens in France on Friday.
Gritsak said the SBU had sold deactivated weapons to the suspect after they found out that he was looking to purchase the arms.
