Hundreds marked the martyrdom anniversary of Prophet Mohammad's grandson, the Chief of Martyrs, Imam Hussein (peace be upon him) in the Austrian capital, Vienna. Imam Hussein (peace be upon him) is the symbol of resistance against oppression. The choice made by Imam Hussein ( peace be upon him) and his small group of family members and companions (peace be upon them), has been a source of inspiration for not just Muslims but for all of humanity, throughout  history.
