Hawzah News Agency -Tasu'a marks the ninth day of the lunar month of Muharram.
In order to honor the occasion, mourners throng around eulogists at religious centers and mosques countrywide, paying their tribute to Imam Hossein (PBUH), a grandson of Islam’s Prophet Muhammad.
The mourners, dressed in black, march in processions and distribute votive food.
Many Shia pilgrims even go on pilgrimage to Iraq, where they take part in mourning rituals at the holy shrines of Imam Hussein, his father Imam Ali and his half-brother Abbas ibn Ali in the cities of Karbala and Najaf.
