Heavy overnight rains wreaked havoc in Pauri district of Uttarakhand killing 20 persons in separate incidents of cloudburst, house collapse and landslides. Army and Air Force may assist in the rescue operation.

About 250 people of Purala Bairagarh village of the district are stranded as all approach roads leading to the village have been "breached", ADM Pauri BS Chahal told PTI, adding the heavy downpour which started late last night was continuing till this afternoon.

The Ganga is flowing just half a metre below the danger mark at 340 metres at Ram Jhula in Rishikesh.
