A wave of bombings mostly targeting Shia neighbourhoods and districts in and around Baghdad killed at least 28 people Sunday, security and medical officials said, updating an earlier toll.
The violence, which also wounded 90 others, struck after around midday (0900 GMT) across the city.
The deadliest violence hit the mostly Shiite neighbourhoods of Amil and Bayaa, both of which are in western Baghdad, the officials said, speaking on condition of anonymity.
The bombings came a day after attacks killed 16 people, nine of whom were shot dead at alcohol shops in Baghdad.
With the latest attacks, the death toll for the first eight days of this month has already surpassed that for the entire month of December last year, according to AFP figures based on security and medical sources.
Violence in Iraq has reached a level this year not seen since 2008, when the country was just emerging from a brutal period of rampant sectarian killings.
