A student holds a portrait of former Indian President A. P. J. Abdul Kalam during a candle light march in Mumbai, India, July 28, 2015. Kalam, considered the father of the country's missile programme, died on Monday in hospital at the age of 83, a doctor said. Popularly known as "Missile Man," Kalam led the scientific team that developed missiles able to carry India's nuclear warheads. He became a national folk hero after helping oversee nuclear tests in 1998 that solidified India's status as a nuclear weapons state. REUTERS/Danish Siddiqui TPX IMAGES OF THE DAY
