DHAKA (AFP) - Floods in southwest Bangladesh have inundated vast swathes of farmland, affecting nearly a million people, many of whom are stranded on embankments with no food or shelter, officials said Tuesday. Heavy monsoon rains in recent days have caused at least five rivers to burst their banks, flooding more than 1,000 square kilometres (400 square miles) of farmland in the remote Satkhira district. "Nearly a million people have been affected by floods in Satkhira. Among them, 120,000 people have been displaced," district administrator M. Abdus Samad said.
