Millions of Iranians have taken part in nationwide processions on Tasu'a, the 9th day of the Muslim month of Muharram, a day before the martyrdom anniversary of Imam Hussain, the third Shia imam.
Shia Muslims hold mourning ceremonies during the first 10 days of Muharram to remember Imam Hussain and his 72 companions, who were all martyred after fighting thousands of soldiers of the ruling tyrant of the time, caliph Yazid in Iraq's plain of Karbala in 680 AD.
Dunning black attire to show their sorrow, Iranians from all walks of life on joined processions that started from the early morning and would last until about midnight.
During the ceremonies, eulogists recite the events of the Battle of Karbala and Islamic scholars elaborate on the underlying messages of Imam Hussain's stance against tyranny.
Muharram ceremonies symbolize the eternal and unwavering stance of truth against falsehood and humanity’s struggle against tyranny, the cause for which Imam Hussain was martyred.
Tasu'a is also known as the day of loyalty and resistance, which was devoted to Abbas Ibn Ali, Imam Hussain's half-brother, in deference to his sacrifices in the battle of Karbala.
