Unidentified gunmen in three cars opened fire at a crowd of pilgrims heading for a Sunni mosque northwest of Baghdad on Wednesday, killing 10 people and wounding 11 others, a well-informed police source told Xinhua.
The bloodshed occurred at about 7:00 p.m. (1500 GMT) while the pilgrims gathered near the Mushahada Mosque in al-Huria district northwest of the capital, the source said on condition of anonymity.
The wounded were taken to nearby al-Kademia hospital, the source added.
Earlier in the day, a car bomb went off at a popular market in southwestern Baghdad, killing five people and injuring eight others.
Sunni Muslims in Iraq started the holy month of Ramadan on Sept. 23, while Shiites began the fasting month two days later.
Ramadan, a month of introspection and piety, has been plagued by a surge in attacks in Iraq over the past three years.
The U.S. military has expected mounting violence in Ramadan this year in the country.
