Thousands of people have gathered at a gymnasium at Oak Creek High School to pay their final respects to the six Sikh worshippers killed at a temple in in the US state of Wisconsin last week.
On Sunday, one woman and five men were killed and three others were wounded when white supremacist Wade Michael Page opened fire at the Sikh temple in the Milwaukee suburb of Oak Creek in Wisconsin.
On Friday, Sikhs and non-Sikhs, many of them wearing kerchiefs on their heads, marched to honor the dead.
Sikh religious leaders recited prayers in the native Indian Punjabi while mourners, many sobbing and embracing, looked upon the open caskets of the members of the Sikh community killed by Page, who then turned a gun on himself.
Those present at the temple were preparing for a special children's service, with a featured guest from India. The attack happened an hour before the service was to start.
