At least 15 people have been martyred and several others injured in separate attacks in the Iraqi capital Baghdad, according to Iraqi security sources.
On Tuesday, several car bombs hit Shia neighborhoods of Baghdad, killing at least seven people, and injuring several others.
No group has claimed responsibility for the Baghdad attacks, but police officials say the main suspects are militants linked to al-Qaeda.
Earlier in the day, eight people were killed in other incidents of violence across the capital.
The United Nations says at least 8,000 people have lost their lives in Iraq so far this year.
On December 25, at least 37 people were killed and over 50 others injured in a series of bomb attacks that targeted Christian areas in southern Baghdad.
Iraq’s Interior Ministry has said that militants have launched an open war in Iraq and they want to push the Middle Eastern country into chaos.
“The country is currently facing an open war from bloodthirsty sectarian forces that aim to plunge the country into chaos,” the Interior Ministry said in a statement issued on July 30, 2013.
