At least 10 Iraqi tourists were killed and dozens more injured in artillery strikes that Turkey blamed on Kurdish militants in the resort town that Turkey claims also houses Kurdish militias

Iraqi President Barham Salih condemned the attack which was carried out at 1:50 p.m. local time on Wednesday, while the country's Ministerial Council for National Security rejected accusations of Kurdish involvement in the incident.

The council further vowed to take steps towards ensuring Iraq's territorial integrity, filing an urgent complaint with the UN, and summoning the Turkish ambassador.

According to a report by Bloomberg News, Turkey invited the Iraqi government to partake in the investigation.

US State Department spokesman Ned Price, in the meantime, urged civilian safety and promised to continue monitoring the crisis.

At a meeting in Tehran on Tuesday, Turkish President Erdogan reiterated his pledge to drive all terrorist groups, including the Kurdish YPG, from northern Syria. Iran, one of the sponsors of the Assad regime, opposes Turkish intervention in the country.

Following their meeting in Tehran on Tuesday, Russia, Turkey and Iran issued a statement, "reaffirming the determination to continue [their] ongoing cooperation in order to ultimately eliminate terrorist individuals, groups, undertakings and entities," according to a statement quoted in an AFP report.

They "expressed their opposition to the illegal seizure and transfer of oil revenues that should belong to Syria".

They also "rejected all attempts to create new realities on the ground under the pretext of combating terrorism, including illegitimate self-rule initiatives, and expressed their determination to stand against separatist agendas" in Syria.

The trilateral statement was released after Erdogan urged his Russian and Iranian counterparts to back his efforts to fight "terrorism" in Syria.

Turkey has launched waves of attacks on Syria since 2016, targeting the Kurdish fighters as well as Islamic State (ISIS) group jihadists.

It has also supported Syrian rebels against the government of President Bashar Al-Assad.

Iran and Russia are also involved in Syria's conflict, but support Assad.
