Speaking on Sunday, acting interior minister Gérald Darmanin said French authorities have so far checked close to one million accreditation requests for the Games that kick off on 26 July and had rejected 4,340 people – some over radical Islamist connections or suspicion of being foreign spies,
RFI reports.
Close to one hundred applicants were rejected over espionage fears or concerns they were agents trying to get an accreditation using a different profession.
In an interview with the weekly Journal du Dimanche, Darmanin said: "They are probably not there to carry out attacks. But in addition to intelligence and traditional espionage, there is the possibility of accessing entry points into computer networks to carry out a cyberattack".
He said they had applied as journalists or technical staff and their countries of origin were Russia and Belarus, among others, which he did not name.
"For example, we refused a large number of 'journalists' who claimed to cover the Games. On the other hand, we accepted the presence of Russians who work for the International Olympic Committee. We apply the precautionary principle," he said.
Russian journalists have been allowed to get accredited for the Games and have already arrived in the French capital.
Paris will be deploying 45,000 security personnel to guarantee safety during the Olympics and its unique opening ceremony along the river Seine where athletes will float on barges past hundreds of thousands of spectators.
Organisers have reduced the initial number of spectators from 600,000 to around 300,000.
