At least 15 people have died and 41 fishermen are still missing across the southern coast of Bangladesh after a storm surge sent 1.5 metre high waves crashing into several towns and villages. 

Thousands of people remained stranded on Saturday as waters inundated homes in the low-lying coastal zone, Bengali-language Kaler Kantha daily reported, quoting officials and witnesses.

The English language Daily Star said that two teenagers had died as a result of the storm in the capital, Dhaka, after a wall collapsed on them.

Giasuddin Ahmed, chief government administrator in the coastal town of Cox's Bazar, said that at least 10,000 islanders had taken refuge in the town after a tidal surge in the Bay of Bengal razed concrete buildings and inundated homes off shore.

Officials in other parts of the region could not be reached for comment.

The weather office in Dhaka said in a bulletin that all fishing boats should remain close to shore.

Bangladesh is a delta nation of 150 million people. Natural disasters like floods and cyclones are common.
