Shia Muslims across the world, including Iran, mark the anniversary of the martyrdom of Imam Hussain, the grandson of Prophet Muhammad, in Karbala, Iraq.
In the ten days leading to Tasu’a and Ashura, cities take on a different look and various ceremonies are held at mosques or special gathering places known as Hussainiya. Muharram ceremonies symbolize humanity’s struggle against injustice and tyranny.
