A series of bombings killed at least 15 people in Baghdad on Sunday, officials said, as militants held a major city and part of another west of the Iraqi capital.

The three car bombs and one roadside bomb, which hit three separate areas of Baghdad, also wounded at least 40 people, the officials said.

The bombings come as militants hold the city of Fallujah, just 60 kilometers (37 miles) from Baghdad, as well as parts of Ramadi, farther west.

Anbar has in recent days seen the worst violence to hit the province in years, killing over 160 people on Friday and Saturday alone.

Violence in Iraq has reached a level not seen since 2008, when the country was just emerging from a brutal period of sectarian killings.
