In Bangladesh, the death toll from flooding and mudslides unleashed by monsoon rains reached nearly 100 on Monday.
Bangladeshi officials say worst hit was the southeastern port city of Chittagong, where 84 people died after many hillside homes were swept away or collapsed under tons of mud.
Telephone lines to the rest of Bangladesh are down, and shops and schools in Chittagong are closed.
Another 15 people were reported killed in other parts of the country by thunderstorms and lightning. Many people are missing, and the death toll is expected to rise as rescue workers search through rubble.
Rescue efforts are being hampered by damaged roads and flooding. June marks the beginning of the annual monsoon season in South Asia which lasts until mid-September.
