NEW DELHI (AFP) - India paid tribute to former prime minister Indira Gandhi on Saturday, the 25th anniversary of her assassination, with politicians and ordinary citizens marking the occasion. Premier Manmohan Singh and Gandhis daughter-in-law Sonia, leader of the ruling Congress party, who cradled Indira in her arms as she was dying, were among those who marked the occasion at memorial sites around New Delhi. Indira Gandhis contribution to nation building and national integration is unparalleled, said Singh in a speech. Sonia Gandhis son Rahul, a key force in the Congress party and a man touted as a potential prime minister, solemnly sprinkled flower petals on a monument dedicated to his grandmother, where multi-faith prayers also took place. Visitors queued up to visit Indira Gandhis sprawling white bungalow residence, which was turned into a museum after the leader, known as Indias Iron Lady, was gunned down by her Sikh bodyguards in 1984. In our country there is no one like her, one man told the CNN-IBN network. She worked so hard but had to suffer, said another visitor. Congress asked members to observe two minutes silence to mark the death of Indira Gandhi, one member of the Nehru-Gandhi political dynasty that has dominated Indian politics for much of the time since India gained its independence in 1947. Deadly anti-Sikh riots followed Gandhis assassination, which was carried out in revenge for her decision to send the army in to evict Sikh separatists from the religions holiest site, the Golden Temple, in Punjab. The state was racked by a violent insurgency at the time.
