Turkey launched its heaviest offensive on Kurdish militants in northern Iraq, since the start of their military campaign in the region.
The strikes hit shelters and depots belonging to the Kurdistan Workers Party (PKK), reports Reuters.
Iraq condemned the air strikes as an “escalation and an assault on Iraqi sovereignty.”
Turkey’s strikes come after it launched an offensive against Islamic State militants, in what it called a “synchronised fight against terror.”
Turkish officials have linked attacks against the PKK to increased killings of Turkish police officers that have been linked to Kurdish militants.
Though Turkey has pledged to provide air cover to Syrian rebels fighting Islamic State militants, it has stressed that it will not provide air cover to Kurdish fighters combating Islamic State advances.
