Warning: some of these images may be distressing for viewers. Tomorrow, millions of Muslims will celebrate Ashura, an important holy day that marks the emancipation of the Israelites from slavery in Egypt; the death of Imam Hussein, grandson of Prophet Muhammad (PBUH), in the year 680 at Karbala in modern-day Iraq; and the day Noah left the Ark. Every year the holiday spawns shocking images of blood and gore, self-inflicted wounds on a communal scale. Did you know it's not only men who take part?
Ashura is observed worldwide for different reasons and in different ways. Sunnis consider it as a day of atonement. For Shiites, the day commemorates the Hussein's martyrdom. It always incites a carnival-like atmosphere with testosterone-charged rituals of bonfires, self-flagellation, and mud-throwing.
Take a look at some of the important roles women and children play in the holy day.
