One soldier succumbed to his injuries after being wounded by a guided anti-tank gun during Operation Pence-Yildirim, said a ministry statement.
Additionally, as a helicopter was landing to deliver supplies, a soldier fell and was injured, it said. Despite doctors' best efforts, he later lost his life in the hospital, it added.
The ministry extended condolences to the families of the martyred soldiers.
Turkey launched Operations Pence-Simsek and Pence-Yildirim on April 23 in northern Iraq’s Metina and Avasin-Basyan regions near Turkey's borders.
The PKK terrorist group often uses bases in northern Iraq just across Turkey's southern border to hide and plot terror attacks in Turkey.
In its more than 35-year terror campaign against Turkey, the PKK – listed as a terrorist organization by Turkey, the US, and the EU – has been responsible for the deaths of at least 40,000 people, including women, children, and infants.
