Amid incessant rainfall in the hill state, a video has surfaced which shows a portion of the Dehradun Defence College building collapsing and being washed away in a swift-flowing stream. Meanwhile, a red alert for heavy rains has been sounded in six districts of Uttarakhand, including Dehradun and Nainital, by the meteorological department.
