Rajouri/ Srinagar/ Kathua/ Sopore, Sep 06 (ANI): Nearly 100 people were killed due to floods in Kashmir, said state Chief Minister Omar Abdullah as all the rivers have been flowing above the danger mark due to incessant rains. Authorities declared a disaster alert in the Himalayan region after two days of heavy rain that hit Kashmir valley, causing the worst flooding in two decades. The police and army have begun rescue operations as floods, triggered by heavy rains, washed away bridges and houses and marooned people. Abdullah said the major challenge was to rehabilitate flood hit victims. Home Minister Rajnath Singh held a meeting in New Delhi to review the flood situation and has dispatched members of the National Disaster Response Force (NDRF) to assist the state government. Singh cancelled trip to the region due to the bad weather.
