Millions of Indians voted Saturday in the next-to-last round of a grueling national election with a combined opposition trying to rattle Prime Minister Narendra Modi’s campaign for a third-consecutive term for himself and his Hindu nationalist party.

Many people lined polling stations before the start of voting at 7 a.m. to avoid the blazing sun at the peak of Indian summer. The temperature soared to 43 degrees Celsius (109 degrees Fahrenheit) in the afternoon in the Indian capital.
