Millions of Shiite Muslims — from Iran to Afghanistan and Pakistan — were marking the festival of Ashoura on Monday, one of the most emotional occasions in their religious calendar, commemorating the 7th century martyrdom of the Prophet Muhammad's grandson Hussein.
Security forces, particularly in Taliban-run Afghanistan, were on high alert for any violence. In the past, bloody attacks have marred the festival across in the Middle East, as Sunni extremists who view the Shiites as heretics seize on the holy day to target large gatherings of mourners.
