At least a thousand people are still stranded at five villages around Chengannur in flood-hit Kerala, even as the weather office has said heavy rain is likely to subside in the coastal state. A few trains packed with people are running between state capital Thiruvananthapuram and Ernakulam, 200 km apart. Floodwater has started receding in some areas. However, the bigger concern now is lack of clean drinking water and diseases due to mosquito infestation, especially in Kochi and Thiruvananthapuram. Commercial flight operations to Kochi also resumed today after the Navy activated its airstrips to accommodate small passenger aircraft. 191 people have died in the Kerala floods since August 8.
