Authorities in Brazil are on high alert as Al-Qaeda-affiliated Islamic terrorists were instructed on social media to carry out ‘lone wolf’ attacks against Israeli, American, British and French athletes in Rio. ‘One small knife attack against Americans/Israelis in these places will have bigger media effect than attacks anywhere else,' they said. ‘Your chance to take part in the global Jihad is here! Your chance to be a martyr is here!’ The murder-inciting message points to the easy process of obtaining travel visas to Brazil and a wide availability of guns in ‘crime-ridden slums.’ Israelis are the biggest targets. ‘From amongst the worst enemies, the most famous is Israelis, Muslims all agree. Spectators are also legitimate targets, but priority should be given to attacking prominent leaders.’
