Sri Lanka is facing one of its worst flood disasters in two decades, with nearly one million people affected and more than 400 reported dead or missing after Cyclone Ditwah unleashed catastrophic flooding and landslides across the island.

 Initial assessments indicate that more than 15,000 homes have been destroyed. Over 200 roads remain impassable, at least 10 bridges have been damaged, and sections of the rail network and national power grid affected.

Flooding along the Kelani River, which runs through Colombo and surrounding low-lying areas, continues to hamper access and disrupt information flow from affected communities, complicating rescue and relief operations.
