Airstrikes by Turkish jets and drones on Wednesday evening killed ten Kurdistan Workers’ Party (PKK) militants in two separate attacks in northern Iraqas announced by the anti-terrorist service of Iraqi Kurdistan.

Last night, “nine PKK militants were killed in a series of airstrikes carried out by Turkish warplanes and drones” in Arbil province, it said in a statement.

Another PKK member was killed in “bombing of facilities” of the organization in Dohuk provinceaccording to the same source who also mentions three injured.

In a statement, the Turkish Defense Ministry said it carried out airstrikes against “terrorist targets” in northern Iraq yesterday, Wednesday.

“A total of 19 targets, including caves, shelters and warehouses used by terrorists and believed to be harboring terrorists, were successfully destroyed and many terrorists neutralized,” he continued.

The Turkish military rarely comments on strikes in Iraq, but regularly conducts ground and air military operations against the PKK and its positions in northern Iraq, autonomous Kurdistan or the mountainous Sinjar region.

Turkey has installed dozens of military observatories on Iraqi soil for 25 yearsbut has been stepping up its drone attacks in recent weeks.

The PKK, which has bases around northern Iraq, is designated a terrorist organization by Turkey, the United States and the European Union. The group launched a guerrilla war in southeastern Turkey in 1984, during which more than 40,000 people have been killed.
