People take pictures of a portrait of former Indian President A.P.J. Abdul Kalam at his school in Rameswaram, India, July 30, 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
