More than 600 people have died in severe floods and landslides across Indonesia, Thailand, and Sri Lanka due to heavy monsoon rains. Indonesia faces the worst hit with over 442 deaths, hundreds injured, and 402 missing on Sumatra Island. Thousands remain stranded without basic supplies. Afrianti, a 41-year-old from Padang, said, "My home and business are gone, the shop is gone. Nothing remains." Rescue efforts are slow as some areas remain unreachable, and aid is arriving by warships. In Thailand, floods killed at least 162 people in one of the worst events in a decade. The government is providing aid and compensation, but criticism is mounting over the flood response. Two local officials were suspended for alleged failures. Sri Lanka also suffers severely as Cyclone Ditwah causes flooding and mudslides, killing at least 212 people and forcing nearly 148,000 to flee their homes. In Colombo, a resident said, "My house is completely flooded. I don’t know where to go." Weather experts link the rising intensity of storms to climate change, which has brought heavier rains and stronger winds across the region. Authorities continue rescue and relief work as they struggle to clear debris and deliver aid. The monsoon season lasts from June to September, often triggering dangerous floods and landslides in these countries.
