The Olympic Games opened in Rio on 5 August amid intense security, and have so far passed with only a few minor incidents. Limited pro- and anti-Rousseff protests were held in ten cities in the week before the Games began. Scuffles broke out at several points during the Olympic torch procession and tear gas and rubber bullets were used to disperse anti-government protesters. Hours before the opening ceremony, several thousand protesters took part in an anti-Temer rally on Copacabana beach and smaller rallies continued outside the Maracanã Stadium. Around 3,000 also gathered close to Copacabana beach in protest at the cost of the Olympics. Temer himself was heckled by spectators at the ceremony and a judge has ruled that protests within the stadia are allowable providing they do not disrupt the events.
Meanwhile, the country remains on high alert due a perceived terrorism threat. An international counterterrorism centre has been set up in Rio for the Games and the US and other allies have stepped up cooperation to monitor the terrorist and cyber threats. On 29 July a Rio resident of Lebanese origin who had travelled to Syria and had alleged ties to Islamic State was arrested. The high state of vigilance was again shown on 6 August when the authorities carried out a controlled explosion on a suspicious bag which turned out to be harmless. The main terror threat remains that of a ‘lone wolf’ attack but we believe the greater risk to visitors is from criminal gangs.
