Multiple bomb blasts have hit northern Iraq, killing at least 10 people in contested areas where tensions have flared between the Kurdish minority and the central government.

Two of the bombs Monday exploded in a Shi'ite area of Tuz Khurmatu, in Kirkuk province. Another blast, a car bomb, struck a Shabak minority area near Mosul.

The attacks follow a string of bombings in Iraq Sunday that killed at least nine people in Kirkuk and Jalula.

Kirkuk is part of the ethnically mixed and oil-rich area that Kurds want to incorporate into their self-administered region, but is also claimed by Turkmen and the Arab-led central government.
