Monsoon rains have caused widespread flooding in northeastern Bangladesh and India, stranding nearly 6 million people and killing at least 19 people in Bangladesh, authorities said on Saturday, warning the situation could worsen.

Monsoon storms in both Bangladesh and India have killed at least 59 people between the two countries, and unleashed devastating floods that left millions of others stranded, officials said Saturday.
