Children play in a pool of water to take a reprieve from the heat in Attari, India near international border between India and Pakistan Saturday, May 18, 2002. India baked in a heat wave Friday so intense that mud huts became as hot as ovens and birds in trees dropped dead, villagers said. This month's heat has killed 638 people nationwide. Officials described the temperatures exceeding 115 degrees as ``a natural calamity.'' (AP Photo/Sandeep Sharma)
