A seven-story residential building collapsed in the north-eastern Brazilian city of Fortaleza on Tuesday, killing at least one person with others still trapped in the rubble.
Five people were found alive and one dead so far, a rescue worker told local TV station GloboNews.
The apartment block fell down at around 10:30 am local time, but it was not immediately clear what caused the accident or how many total victims may be involved.
Fire brigade and civil defence were not immediately available to provide further details.
Television footage showed a handful of rescuers in orange suits digging through a massive pile of wreckage in a middle class area of Fortaleza, the capital of Ceara state.
According to G1 news website, pedestrians who were passing by the building when it collapsed were taken to nearby medical clinics and access to streets surrounding the wreckage were closed by authorities.
