Rio de Janeiro

A large-scale bomb attack was thwarted by police before Gaga's first concert in Brazil since 2012.

More than two million people attended the concert on Copacabana beach in Rio de Janeiro, city officials say.

The concert on Copacabana beach was paid for by Rio de Janeiro city to help boost the economy.

Crowds filled the Sambadrome to watch samba schools face off at Rio Carnival.

At least 20 people have been injured after a factory making costumes for Carnival celebrations in Brazil caught fire.

Brazil's justice minister said the homicide was "evidently politically motivated".

Officers are investigating whether organised crime gangs are involved in running the machines.

The show at Rio de Janeiro's Copacabana beach was the final stop on the pop idol's Celebration Tour.
