In Tehran, the streets come alive with somber displays of faith as Shia Muslims worldwide commemorate the martyrdom of Imam Hussain.

Millions of Muslims join mourning ceremonies worldwide to mark Tasu’a, which precedes Ashura, the day of the martrydom of Imam Hussein (AS), the third Shia Imam.

This year’s Arbaeen congregation in the Iraqi holy city of Karbala hit a record high as millions streamed into the city after walking by foot from the holy city of Najaf, a shrine official tells Press TV website.

Through the lenses of several foreign tourists from different countries, the documentary shows the mourning ceremony of Imam Hussain (AS) in Yazd, Iran.

The history of Ta'zieh, a kind of passion play, and its evolutionary trend in the Iranian context are probed into focusing on its constituent components: writing style, directorship, set and costume design, music, and acting style.

Thousands of Shia mourners gathered in the city of Milan in northern Italy on Sunday to commemorate Ashura, the tenth of Muharram.

Ashura was the fountainhead of Imam Khomeini’s revolutionary ideology and his popular call for fighting Taghut, a Quranic term denoting tyrannical powers on earth.
