Erdoğan vowed that Turkey will continue operations against the PKK and the YPG, similar to strikes earlier this week on Mt. Sinjar in northern Iraq and Syria's Mt. Karaçok.

Forty militants were killed at Iraq's Mt. Sinjar and another 49 at Syria's Mt. Karacok in April 25 airstrikes by Turkish forces against the PKK, the Democratic Union Party (PYD), and its armed wing the YPG.
