A plane reportedly carrying the Brazilian presidential candidate Eduardo Campos has crashed in a residential area of the port city of Santos, in Brazil’s Sao Paulo state.
The plane was frequently used by Mr Campos who is running for president for the Brazilian Socialist Party (PSB).
Party members said he was on board at the time of the crash.
Firefighters said there were 10 “victims” but did not clarify if the 10 were injured or dead.
Friends and colleagues of Mr Campos said they were “very worried” by the fact they had not been able to make contact with Mr Santos since the crash.
PSB member Rodrigo Rollemberg said Eduardo Campos had been on board the plane along with his wife Renata, and his son Miguel.
According to Mr Rollemberg, two assistants and a film-maker were also travelling with Mr Campos.
A police spokeswoman told the AFP news agency that there were “fatalities but we still do not have a number confirmed”.
Locals said the sky was cloudy and it was raining at the time of the crash.
Police and emergency workers are at the scene in Santos, which is located 70km (43 miles) south-east of Sao Paulo.
The Cessna 560XL plane had taken off from Rio de Janeiro’s domestic airport and was heading to the city of Guaruja, near Santos, the Brazilian Air Force said.
According to Air Force officials, air traffic control lost contact with the plane after it could not land in Guaruja due to bad weather.
