BAGHDAD, Dec. 25 (UPI) -- Iraqi authorities said three Shiite pilgrims were killed and 20 others were wounded by a roadside bomb Friday in Baghdad.
Officials with the Iraqi Ministry of Information said the incident was the latest in a series of attacks targeting Shiite pilgrims in the run-up to the holy day of Ashura, CNN reported Friday.
The officials said recent years have seen frequent attacks on Shiite pilgrims traveling to Baghdad and the city of Karbala for Ashura, which commemorates the martyrdom of the Imam Hussein, grandson of the Prophet Mohammed, in 680.
Meanwhile, the Iraqi Interior Ministry said three teachers working for the country's census committee were killed by gunmen in Mosul while conducting interviews with families.
An Interior Ministry official said a fight broke out in Bartela after a group of Christians began taking down black flags symbolizing Ashura. Five Christians and five Shiites were hospitalized with injuries.
