Five car bombs at Iraqi mosques kill at least 17

Car bombs at four mosques in the Iraqi capital Baghdad and a fifth in the Kurdish town of Kirkuk have killed at least 17 people and wounded many more, according to police and witness accounts.

Police said the blasts hit Shi'ite mosques in southeastern and northern Baghdad and another in Kirkuk, the ethnically mixed city in the autonomous Kurdish region.

Sunni Islamists linked to al-Qaeda's Iraqi wing have stepped up attacks this year and often target Shi'ite sites in a growing sectarian confrontation a decade after the US-Led invasion.
