BAGHDAD, Sept 11 (Reuters) - A car bomb exploded near a Shi'ite mosque in the Iraqi capital on Wednesday evening, killing at least 15 people, police and medical sources said.
A further 27 were wounded in the blast, which took place in the northwestern Kasra district of Baghdad.
It was not immediately clear who had carried out the attack, but Sunni Islamist militants who view Shi'ites as non-believers, have been regaining momentum and striking on a near daily basis this year.
More than two years of civil war in neighbouring Syria have brought sectarian tensions to the boil in Iraq and the wider region.
About 800 Iraqis were killed in August, according to the United Nations, with more than a third of the deadly attacks happening in Baghdad.
The bloodshed, 18 months after U.S. troops withdrew from Iraq, has stirred concerns about a return to the sectarian slaughter of 2006-07, when the monthly death toll sometimes topped 3,000. (Reporting by Kareem Raheem; Writing by Isabel Coles; Editing by Alison Williams)
