PARIS, Aug. 20 (Xinhua) -- Some 13,200 policemen and gendarmes will be deployed in the city of Biarritz in southern France where the G7 summit will be held from August 24 to 26, said French Interior Minister Christophe Castaner on Tuesday.
Soldiers will carry out counterterrorism missions both on land and at sea, supported by the Spanish authorities of law enforcement. More than 400 firefighters and 13 teams of emergency service and civil security associations will also be mobilized, the minister told a press conference.
He mentioned "three major threats within each major international meeting" -- risk of overflow, terrorist threat and cyber-threat.
"We do not have a particular terrorist alert, but the risk is constant," he stressed. "Our vigilance is maximum."
The Spanish authorities are in exceptional cooperation with the French to prevent potential violent rallying, he added.
Five people suspected of wanting to attack members of the security forces during the G7 were arrested Monday. They broadcast messages on social media calling to burn a hotel in which mobile gendarmes stay.
Aged from 24 to 45, the five individuals, including a woman, were arrested in Tours in central France, and in Capbreton, a southwestern commune on the Atlantic coast. Four of them were released on Tuesday afternoon while the main suspect remain in custody.
