Floods have engulfed two states in north-east Brazil, leaving about 1,000 people missing and forcing at least 100,000 to flee their homes.

At least 38 people are known to have died so far in Alagoas and Pernambuco.

Correspondents say the floods, brought on by nearly a week of rain, have washed away entire villages.

The governor of Alagoas, Teotonio Vilela Filho, said bodies were being washed up on beaches and riverbanks.
