New Delhi CNN —India’s relentless heat wave killed 33 poll workers as the country concluded its final day of voting in the world’s largest general election, officials said, underscoring the impact of searing temperatures in recent days. Voters and election workers have endured an extended period of unusually high temperatures across much of the country’s north as India voted in a seven-phase election that began on April 19. Of that number, at least 43 were election workers, authorities said. The capital territory of Delhi sweltered to its highest-ever temperature of 49.9 degrees Celsius (121.8 degrees Fahrenheit) last week, as the oppressive heat wave forced authorities to impose water rationing. “Heat wave conditions over Northwest, Central & East India are likely to continue with reduced intensity during next 3 days,” the Indian Meteorological Department said on Sunday.
