The death toll from last weekend's flash flooding in the southern Brazilian town of Itaoca has risen to 20, with six people still missing, authorities said .
Sao Paulo state's Civil Defence Department updated the earlier toll of 12 dead.
Some 332 people - or about 10 per cent of the town's population - were left homeless by overflowing waters from the Palmital River following torrential downpours.
Four people were injured and some 100 homes damaged.
A bridge providing access to Itaoca, located 340 kilometres southwest of Sao Paulo, was also destroyed and state authorities yesterday pledged to rebuild it.
