Sikhs wielding knives and a handgun attacked two preachers at a rival temple in Vienna on Sunday in a brawl that left at least 16 people wounded, police and witnesses said. A related clash later broke out in northern India. Witnesses said a group attacked their religious leaders at the temple in Austria's capital and their followers moved to defend them. The preachers were among the six people who suffered serious wounds and were identified by Indian diplomats and police as Nirajnan Das and Sant Rama Anand. Police said both were out of danger after undergoing operations for gunshot wounds. Police spokesman Michael Takacs said the scene was “like a battlefield.” Six suspects were in custody with more arrests possible, he said. Mohnder Ram, a worshipper who said he had attended services at the temple for decades, said it is run by followers of Shri Guru Ravidas, a 14th-century founder of a Sikh sect called Dera Sach Khand. In India, fighting between mainstream Sikhs and followers of the guru broke out in the northern city of Jalandhar, in what locals there described as an apparent reaction to the melee in the Austrian capital.
