Brazilian security chiefs have brought in the Israeli special forces to help guard against a terror attack at the Olympic Games, which officially begin on Friday.
More than 10,000 soldiers and police have received special training from the elite troops and private contractors who are skilled in dealing with terror threats.
Reports from Israel reveal their security teams have also provided state-of-the art monitoring and tracking equipment to keep tags on terror suspects.
Troops and ex officers from the Israeli special forces are believed to be among those working with the Brazilian army.
The Israeli experts will not be on duty during the Games, but were said to be involved in troop training at least up until May.
Then the ‘contract’ was said to have been put on ice following protests from the Palestinians.
But reports in Israel claim up to 35 private security firms are still involved in providing some kind of security help.
Two weeks ago, al-Qaeda sympathisers issued a list of directives on social media calling for their followers to carry out “lone-wolf” attacks against American, British, French and Israeli athletes, using knives, poison, explosives-laden drones and kidnappings.
The instructions also specified why the group’s followers should target Israeli athletes and spectators.
“One small knife attack against Americans/Israelis in these places will have bigger media effect than any other attacks anywhere else, inshallah [God willing],” one of the directives read.
