Indonesia is facing a mounting humanitarian emergency after catastrophic floods killed at least 631 people and left nearly 500 missing, with rescue teams still struggling to reach isolated communities. Triggered by a rare cyclone over the Malacca Strait, the disaster has affected some 1.5 million people across Aceh, North Sumatra, and West Sumatra, cutting off entire districts and leaving about one million people displaced. Survivors describe torrents of water like a ‘tsunami’, while images show bridges swept away, roads buried in mud, and debris piled high. Many families have gone days without food as red tape, damaged infrastructure, and ongoing storms hinder aid deliveries. Grieving relatives wait anxiously near excavation sites, hoping missing loved ones will be found. Anger is growing over what critics say was poor preparedness and environmental mismanagement which worsened the devastation. The flooding comes as part of a broader regional crisis, with over 1,200 deaths across south and southeast Asia caused by intense monsoon rains amplified by rare cyclones and a warming climate.
