At least four artillery shells struck the resort area of Barakh in the Zakho district in the semi-autonomous Kurdish-run region, District Mayor Mushir Mohammed told The Associated Press. All the casualties were Iraqi citizens.

Iraq's military said eight were killed in the attack. Health workers at the Bidar Hospital in Dohuk province, which received patients, said nine were killed.

Dozens of wounded people sat outside the hospital. Critically injured patients, including young children with stunned faces, were transferred in gurneys. Inside, a toddler was pronounced dead along with her mother.

Among the wounded was Yousef, a tourist from Baghdad. He said many tour groups were vacationing in the area at the time of the attack.

Iraq's government condemned the attack, calling it a ``flagrant violation of Iraq's sovereignty,'' according to a statement from the Foreign Ministry.

Separately, six federal police personnel were killed and five were wounded in the northern province of Salahadin after Islamic State militants attacked their units at dawn on Wednesday, according to two officials in the Iraqi army who spoke on conditon of anonymity because they were not authorized to speak to the media.

Hundreds of Iraqi tourists come to the Kurdish region from the south during the peak summer months because the weather is relatively cooler.

The touristic sites in Zakho is nearby military bases set up by Turkey.

Prime Minister Mustafa al-Kadhimi dispatched a delegation to the area lead by Foreign Minister Fuad Hussein and ordered an investigation into the incident.

Turkey regularly carries out airstrikes into northern Iraq and has sent commandos to support its offensives targeting elements of the outlawed Kurdistan Worker's Party or PKK.

Wednesday's attack marked the first time that tourists had been killed in the frequent attacks by Turkey in the area, the officials said. Turkish strikes in the area are common and have killed civilians, mostly local villagers, there before.

In April, Turkey launched its latest offensive, named Operation Claw Lock, in parts of northern Iraq - part of a series of cross-border operations started in 2019 to combat the outlawed PKK who are based in the mountainous regions of northern Iraq.

The PKK, which is listed as a terrorist organization by Turkey, the United States and the European Union, and has led an insurgency in southeast Turkey since 1984 which has killed tens of thousands of people.

Ankara has pressed Baghdad to root out PKK elements from the northern region. Iraq, in turn, has said Turkey's ongoing attacks are in breach of its sovereignty.
