Two separate car bombs struck commercial areas in Baghdad leaving nine people dead and nearly 20 others injured on Wednesday.
Nine others lost their lives and dozens more, including women and children, were injured by separate blasts near a pastry shop and a restaurant.
Militants randomly opened fire on pedestrians in a Shia-Christian neighborhood in the southeast of the capital, killing two and injuring several others.
Meanwhile, the country’s security forces supported by Sunni tribesmen have been battling the militants in the western province of Anbar.
The violence in Anbar broke out on December 30, 2013, when the army removed an anti-government protest camp in Ramadi. Authorities said the camp was used as "headquarters for the leadership of al-Qaeda." The bloodshed later spread to nearby Fallujah.
The Iraqi government has stepped up efforts to boost security across the country over the past few months.
