Sao Paulo (CNN) -- At least six people died when a building collapsed in Sao Paulo, Brazil, Tuesday, a state security spokeswoman said.
The building was under construction at the time of the collapse and the victims were workers on the site, said Celia Jacysyn, spokeswoman for the Sao Paulo security secretariat.
At least 20 people were injured in the collapse, according to state-run Agencia Brasil news agency.
Eight people remain unaccounted for, Jacysyn said.
There were 35 people working on the construction of the building when it collapsed, Jacysyn said.
The two-story commercial building was in the final phases of construction, an employee of a neighboring business told Agencia Brasil.
Sao Paulo is the largest city in Brazil and the country's business and financial center.
Another deadly collapse happened in Rio de Janeiro last year. In that incident, a 20-story building collapsed along with two neighboring buildings. Three people died in that collapse.
