Washington, Aug. 6 : Sikhs residing in the United States are in a state of shock over a gunman killing six people and injuring three others at a Sikh temple on Sunday in the Milwakee suburb of Oak Creek.

Witnesses said the gunman fired as soon as he entered the kitchen of the temple.

According to New York Daily News, Mohan Singh Khatra''s 70-year-old uncle was among the six people killed in the attack.

Khatra, the chairman of the Sikh Cultural Society, said he had spoken to his uncle just last night, and was expecting to stay at his house for a wedding.

Now, he, along with other members of the society, may instead have to attend his funeral.

"I''m still in shock. It''s a bad situation, it''s really sad," Khatra said.

Other Sikhs, who were celebrating the anniversary of Sikh saint Isher Singh Rarewale, were stunned by the attack.

"Whatever happened there, was not right," Joginder Singhriar, a preacher at Baba Makhan Shah Lubana Gurdwara Sikh center, said.

"What we are doing is something right in the name of God and what happened is not fair," he added. (ANI)
