Plummeting mercury, coupled with a thick fog cover, threw normal life out of gear in the entire North India on Monday, with 24 more people succumbing to the chill in various parts of the region.

While 20 more people died in Uttar Pradesh, four persons lost their lives in Uttarakhand, said officials. Delhi continued to shiver with the mercury below normal in the city by five notches to settle at 2.4 degrees Celsius, even as it rose from Sunday’s 1.9 degrees Celsius.
