A suicide bomber attacked a Shi'ite shrine in Iraq on Tuesday, killing 11 people, including some mourning seven who were shot dead earlier in the day.
The blast at the Abu Idris shrine in Baquba, northeast of Baghdad in the religiously and ethnically mixed province of Diyala, also wounded 19 people, sources said.
Victims included people who were mourning the deaths of seven Shi'ite shepherds gunned down northeast of Baquba earlier on Tuesday.
Members of Iraq's Shi'ite majority are frequently targeted by Sunni militants, who consider them to be apostates.
In Baghdad, a roadside bomb exploded near a market on Tuesday, killing one person and wounding five, while gunmen shot dead a police officer and wounded two more near Ramadi, west of the capital.
With more than 6350 people killed since the beginning of the year, according to AFP figures, violence has reached a level not seen since 2008, when Iraq was emerging from a period of brutal sectarian killings.
The surge in violence has raised fears the country is falling back into all-out conflict.
It took eight days for this month's death toll to surpass that for the entire month of December last year, according to AFP figures based on security and medical sources.
Officials have blamed the violence on Al-Qaeda-linked militants emboldened by the civil war in neighbouring Syria, but analysts and diplomats also say the government has not done enough to address underlying domestic grievances fuelling the violence.
Members of the country's Sunni minority, who complain of discrimination at the hands of the Shi'ite-led government, have held demonstrations for almost a year.
