Millions stranded in deadly Bangladesh floods

STORY: About 105,000 people have been evacuated so far, but police officials estimated that over four million were still stranded. Thousands of policemen and army personnel have been deployed to parts of the country to help search and rescue efforts.

Many of Bangladesh's rivers have risen to dangerous levels and the runoff from heavy rain from across Indian mountains exacerbated the situation, said the head of the state-run Flood Forecasting and Warning Center.

Environmentalists warn climate change could lead to more disasters, especially in low-lying and densely-populated Bangladesh.
