Declare Chennai floods as national disaster: Kanimozhi

New Delhi, Dec 2: DMK MP Kanimozhi Karunanidhi on Wednesday asked the central government to declare Chennai floods as a national disaster. "The situation is grave in Chennai. The central government should declare it as national disaster," the Rajya Sabha MP said. "The work done by the central government is commendable, but more needs to be done," she added. Unprecedented torrential rains, the worst in 100 years, have battered Tamil Nadu's northern districts including Chennai, Tiruvallur, Kanchipuram and Cuddalore. In the last spell of rains, around 180 people died in the four districts. A fresh downpour worsened an already disastrous flood situation, posing danger to thousands in low-lying areas.
