Operation Blue Star

After several futile negotiations, Indira Gandhi ordered the Indian army in June 1984 to enter the Golden Temple in order to remove Bhindranwale and his supporters from the complex. The army used heavy artillery, including tanks, in the action code-named Operation Blue Star. The operation badly damaged or destroyed parts of the Temple complex, including the Akal Takht shrine and the Sikh library. It also led to the deaths of a large number of Sikh fighters and innocent pilgrims. The number of casualties remains disputed with estimates ranging from many hundreds to many thousands.
