Floods unleashed by days of unseasonal heavy rain have wrecked crops, blocked roads and washed away bridges in northern India, killing at least 46 people, officials said on Wednesday, as they mounted rescue efforts for those stranded. Aerial images gave glimpses of engorged rivers and partially submerged villages in affected areas in the Himalayan state of Uttarakhand, Reuters reported. "The locals are facing a lot of problems, the roads are waterlogged, bridges have been washed away." Footage from national disaster management officials showed people being led to safety after being trapped in landslides. Prime Minister Narendra Modi was anguished at the loss of life, he said on Twitter.
