Thousands of police in at least 14 Brazilian states have walked out on strike today – less than a month before the start of the World Cup.
The nationwide industrial action over pay affects several World Cup host cities, including Sao Paulo, where the tournament will begin on June 12, and Rio de Janeiro.
Only civil police, who deal with criminal enquiries, are reported to be taking strike action; demanding a pay rise of up to 80%.
The Foreign and Commonwealth Office advised British travellers in Brazil to monitor local media for updates and advice.
Tourists should also check with their airline if they have flights booked, the FCO said.
However, military police, who patrol the streets, and federal police, who are in charge of the borders and airports, say they have grievances but are not planning any strike until the end of the month-long World Cup.
Authorities in Rio – where the England team will be based – earlier announced the city’s security plans for the World Cup.
Up to 20,000 people, including military police and soldiers, will be used to guarantee safety in the city during the event, the BBC reported.
