More than 350 people have now been killed by flooding and mudslides in south-east Brazil, say officials. In the mountain towns of Nova Friburgo, Teresopolis and Petropolis, the reported death tolls are at least 168, 152 and 36 respectively, Brazilian media reported. Rescuers are bringing helicopters in as the search for survivors continues in the region north of Rio de Janeiro. Brazil has seen severe flooding in recent years, affecting thousands. Heavy rain began falling again early on Thursday as rescuers began their search and is expected to continue throughout much of the day. Brazil's civil defence department has not yet confirmed the higher death toll, but officials there have said they believe there could be hundreds more bodies yet to be recovered in Teresopolis alone, the Globo media organisation reported.
