STORY: The dispute centers on a building in Kirkuk that was once the headquarters for the Kurdistan Democratic Party (KDP) but which the Iraqi army has used a base since 2017.

The central government plans to return to the building to the KDP in a show of goodwill but Arab and Turkmen opponents set up a camp outside the building last week in protest.

The violence was sparked when a group of Kurdish protesters approached the camp on Saturday, police said.

Police and hospital sources had said earlier that one Kurdish protester was killed. The death toll rose after two more Kurdish protesters died in hospital from bullets wounds, they said.

Security officials and police in the city say they were investigating the circumstances of the deaths, including who opened fire. People from both protest groups were wounded as stones were thrown and metal bars used to attack, Kirkuk police said.

Kirkuk, an oil-rich province in northern Iraq along the fault lines between the Kurdish autonomous region and areas controlled by Iraq's Shi'ite-dominated central government, has been the focus of some of the country's worst post-Islamic State violence.
