Rio De Janeiro, June 2: The Brazilian government has not detected any threat of terrorist activity in Rio de Janeiro -- the venue for the 2016 Olympic games in August, a defence officer said.

Brazil's armed forces and federal intelligence body Abin have been monitoring international terrorist groups following recent attacks in Paris and Brussels, the official said on Wednesday, Xinhua news agency reported.

In April, Abin said it had identified an Islamic State (IS) terrorist who posted messages on social media alluding to the Olympic Games.
