The blasts killed at least 14 people and wounded 106, a medical official said. He spoke on condition of anonymity because he was not authorized to release the information.

The death toll for the month of June is the second highest so far in 2012, rivaled only by January, when 198 Iraqis were killed in a series of blasts widely seen as al-Qaida's attempts to shock the country immediately after the last American troops withdrew in December.

The absence of international forces combined with the government divisions and weak Iraqi security have emboldened the militants, said Stephanie Sanok, an analyst at the Center for Strategic and International Studies who formerly worked at the U.S. Embassy in Baghdad on governance issues.

"The insurgents are now more complacent in the knowledge that international forces are not going to come riding back in," she said.
