Kerala should be treated on a different yardstick for extending flood relief assistance, as its huge loss cannot be compared with damage in any other state at any point of time, Chief Minister Pinarayi Vijayan said on Friday.

Giving a detailed account of the havoc caused by the floods, he said the preliminary assessment of losses was around Rs 20,000 crore, which was equal to the state's annual plan size for 2018-19. The heavy rains and floods have claimed 231 lives in Kerala since August 8 and more than 10.40 lakh people are still in relief camps across the state.
