Ukraine's state security service said on Monday a French citizen detained in late May on the border with Poland had been planning attacks in France to coincide with the Euro 2016 soccer championship it is hosting. The Ukrainian border guard service reported on Saturday that 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 Vasyl Hrytsak said the man had made contact with armed groups in Ukraine with the aim of buying weapons and explosives. In Paris, a French police source said a raid on the suspect's home in France had uncovered ingredients for homemade explosives. His intended targets included Jewish and Muslim places of worship and buildings involved with the soccer tournament, Hrytsak 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 globalisation, and also talked about plans to carry out several terrorist attacks," Hrytsak told journalists.
