Portugal Colonial - Iraq condemns 'repeated Turkish attacks' after Kurdish officers killed

"The Turkish ambassador will be called in to receive a letter of protest addressed to the Turkish president", Recep Tayyip Erdogan, Rashid's office said in a statement.

"Mercy be on the martyrs of Iraq, the civilian and military heroes killed by repeated Turkish attacks."

Turkish authorities have not commented on Monday's strike which killed three members of the counterterrorism forces of Iraq's autonomous Kurdish region and wounded three others at Arbat airfield, southeast of the city of Sulaimaniyah.

While such attacks against the Iraqi Kurdish security services are extremely rare, Ankara is leading a quickening campaign in northern Iraq and neighbouring Syria, targeting Kurdish fighters.

A senior military official in Baghdad said that the drone which killed the counterterrorism officers had originated in Turkey.

Around 5:00 pm (1400 GMT) on Monday, "the drone entered Iraqi airspace, crossing the border from Turkey, and bombarded the Arbat airfield," which is mainly used by crop-spraying aircraft, said General Yehya Rassoul, spokesman of the federal armed forces commander in chief.

"This attack constitutes a violation of Iraq's sovereignty", he said, adding: "Iraq reserves the right to put a stop to these violations."

"These repeated attacks are incompatible with the principle of good neighbourliness between states. They threaten to undermine Iraq's efforts to build positive and balanced political, economic and security relations with its neighbours," Rassoul said.

On Sunday, a Turkish drone strike killed a senior official and three fighters of the Kurdistan Worker's Party (PKK) in the Sinjar Mountains of northwestern Iraq, Iraqi Kurdish authorities said.

Ankara and its Western allies classify the PKK as a "terrorist" organisation.

The United Nations mission in Iraq condemned the attack on Arbat airfield.

"Attacks repeatedly violating Iraqi sovereignty must stop," it said. "Security concerns must be addressed through dialogue and diplomacy -- not strikes."

The Turkish army rarely comments on its strikes in Iraq but routinely conducts military operations against PKK rear-bases in autonomous Kurdistan as well as in Sinjar district.

The PKK has been waging a deadly insurgency against the Turkish state for four decades and the conflict has repeatedly spilt across the border into northern Iraq.

Turkey operates dozens of military posts in northern Iraq initially established under an agreement struck in the eighties with the government of executed dictator Saddam Hussein.

In April, Baghdad accused Ankara of carrying out a "bombardment" near Sulaimaniyah airport while US soldiers and the commander of the Syrian Democratic Forces -- a US-backed alliance dominated by the PKK's Syrian Kurdish ally, the People's Defence Units (YPG) -- were present.

That strike too drew condemnation from the office of president Rashid, who is himself a Kurd.
