Inside the temple complex, plainclothes policemen mingled with devoteesand relatives of the people killed in Operation Blue Star, as the armyaction was called. Outside, police frisked the devotees as they enteredthe temple's huge gates.

Armed police guarded the paths leading up to the temple located in thenorthern Indian city of Amritsar.

The prayer meeting, held to coincide with the 16th anniversary of thestorming of the temple, passed peacefully.

Giani Joginder Singh Vidhanti, the head priest of the Golden Temple,conducted the prayer service and honored the dead separatists asmartyrs.

"The martyrs of 1984 have made the community proud and have continuedthe Sikh tradition of sacrifices," he said.
