Storms have battered areas of Bangladesh AFP

Cyclone Bulbul has ripped through coastal areas of Bangladesh and India, killing at least 13 people while more than two million others were forced to spend a night in storm shelters.

The storm packed winds of up to 120km/h (75 mph), injuring dozens and destroying thousands of homes.

Five of the six who lost their lives in Bangladesh were hit by falling trees.

Officials say that further casualties were avoided because people were evacuated in time.

Authorities say the storm is now weakening.
