Two Sikhs sentenced to death for the 1984 assassination of Indian Prime Minister Indira Gandhi won’t be executed until President Ramaswami Venkataraman rules on a petition for mercy, the United News of India reported. Satwant Singh and Kehar Singh were scheduled to be hanged Oct. 19. The news agency, quoting an unidentified government spokesman, said a new date for the executions will be announced if the petition is rejected. The mercy plea was filed by Kehar Singh, 54, but both executions will be stayed, the agency said. Satwant Singh, 24, has refused to file a similar plea.
