At least 11 people were wounded when armed men attacked the preacher and worshippers at a Sikh temple in Vienna on Sunday, police and the Austrian national news agency APA.
APA quoted police spokesman Michael Takacs as saying all suspects had been arrested after the incident in the Austrian capital mid-afternoon.

Local authorities and witnesses initially said the assailants were from two feuding families but later said it involved members of several rival Sikh temples in Vienna who had been at odds for several years.

Police said the violence began when six people burst into the temple in Vienna's Rudolfsheim district during a religious service and attacked the preacher and other worshippers, one of them firing a gun and others wielding knives.

In ensuing violence, at least 11 people suffered gunshot and stab wounds before the assailants were subdued, they said.

One of the attackers was in critical condition.
