DHAKA (AFP) - At least four people were killed and more than 200,000 stranded after three days of heavy rains triggered flash floods and landslides in southeastern Bangladesh, officials said Friday. The government's flood forecasting and warning centre said more than 49cm of rain had pounded the worst-hit Cox's Bazaar district since Wednesday, flooding at least 200 villages in the hilly region. "One child was buried under mud due to landslide and three more people were washed away in the huge torrents of water," Cox's Bazaar chief district administrator Zainul Bari told AFP.
