Police in northern Iraq say security forces have killed at least two people and wounded several others who were protesting a rise in fuel prices and lack of basic services in the city.
Authorities say on Sunday's riot broke out in a mainly Kurdish district of Kirkuk, as angry protesters set fire to several gas statsions and an oil company building in the city. Police later imposed a curfew.
In Baghdad, a bomb blast near one of Iraq's largest oil refineries triggered a pipeline fire that threatened to worsen the country's oil crisis. The bombing was the second in recent days.
Meanwhile, Iraqi police say at least 11 car bombs -- most of them in Baghdad -- exploded today, wounding at least 20 people.
