Men relax after applying mud on their bodies to cool themselves off on a hot summer morning on the banks of the river Ganges in Allahabad, India, June 3, 2015. Temperature in Allahabad on Wednesday is expected to reach 44 degree Celsius (111.2 degree Fahrenheit), according to India's metrological department website. India's earth sciences minister has blamed climate change for a heatwave that has killed 2,500 people and for deficient monsoon rains, after the government said on Tuesday the country was headed for its first drought in six years.
