The Belgian royal couple has been prevented by Brazilian authorities from visiting a charity project in one of Rio de Janeiro's favelas, a Brazilian report said.
Authorities said the favela where Friday's planned visit by King Philippe and Queen Mathilde was to have taken place is too dangerous, O Globo daily reported in its online edition late Thursday.
The royal couple wanted to visit a Belgian-funded project at Morro dos Mocacos in the particularly dangerous northern zone of the Olympic city.
According to the report, the Belgian ambassador tried to put pressure on the Brazilian Foreign Ministry to make the visit possible.
The ministry however insisted security forces would be focusing on Friday's Olympic Games opening ceremony. The royal couple then called off the visit.
