An apartment building has fallen in the city of Recife in north-eastern Brazil, killing at least 14 people, rescuers say.

Two children, aged five and eight, were among the casualties when the block disintegrated on Friday.

The cause was not immediately clear, but Recife has been pounded by heavy rain in recent days.

Reports say three people were rescued from the rubble and six are as still missing in the Janga area.

The collapse happened in Recife's Paulista suburb, where some residents called this type of four-storey building a "coffin block", complaining of poor construction.

Officials said the building collapsed at around 06:35 local time on Friday (09:35 GMT) when many residents would have been sleeping.

Globo News says the victims also included a 43-year-old mother and her 19-year-old son.

The local governor said on Friday that more rain was expected and that people should make sure they can get to safe structures.
