Authorities say the death toll from two car bombs in an ethnically disputed city in northern Iraq has risen to 13.

The deputy police chief in the city of Kirkuk, Maj. Gen. Torhan Abdul-Rahman Youssef, says more than 100 people were wounded in the two blasts Wednesday.

He says the deadliest of the two explosions killed 11 when it struck the local headquarters of the Kurdistan Democratic Party. The KDP is led by Massoud Barzani, the president of Iraq's largely autonomous Kurdish region, who has frequently sparred with Iraq's central governor in Baghdad.

It was followed by a second car bomb explosion nearby, which killed two more people.

Kirkuk is located 290 kilometers (180 miles) north of Baghdad.
