Ankara and Tehran have opened parallel investigations into the shooting, Türkiye’s Ministry of National Defense said on Thursday.
Infantry Contracted Private Yusuf Sait Ünlü was responding to an illegal crossing at the Engin Mayın border outpost when he was hit, according to the ministry.
“In the area of responsibility of the Engin Mayın Border Outpost on the Türkiye-Iran border, on Oct. 31, 2026, during an intervention in an illegal crossing, Infantry Contracted Private Yusuf Sait Ünlü was killed as a result of fire assessed to have come from the Iranian side,” the ministry said.
Attribution Added Five Days Later
The statement came from spokesperson Rear Adm. Zeki Aktürk at the ministry’s weekly briefing in Ankara on Nov. 5.
It added a detail missing from the ministry’s first account. On Oct. 31, officials said only that Ünlü, assigned to the 7th Border Brigade Command, was wounded by gunfire during a border-crossing incident in Esendere, in Hakkari province’s Yüksekova district.
That account did not identify who fired.
Ünlü was airlifted to Hakkari State Hospital, where he died despite treatment. He was buried in Çine, his hometown in Aydın province.
Parallel Investigations
“Immediately after the incident, a judicial and administrative investigation was launched, and on Nov. 3, 2026, a meeting was held with Iranian officials at the scene,” the ministry said.
Iranian authorities have opened their own judicial and administrative inquiry, according to the ministry.
“Efforts to clarify all aspects of the incident are being carried out meticulously in coordination with Iranian authorities,” the statement added.
The ministry extended condolences to Ünlü’s family, the Turkish Armed Forces and the nation.
Border Patrols and Precedent
The mountainous Hakkari frontier with Iran is a focus of routine patrols against illegal crossings and smuggling.
In June 2020, gunfire from the Iranian side killed one Turkish soldier and wounded two others during a reconnaissance mission in the same Yüksekova district, Rudaw reported.
At the briefing, the ministry said 665 people had been caught at the borders in the recent period, eight of them members of terrorist organizations. Another 1,766 were stopped before crossing.
The incident comes amid wider regional strain over Iran, including Russia’s reported agreement to supply Tehran with missile launchers and Washington’s stance on resuming the Iran war.
Aktürk also offered condolences for Infantry Specialist Sgt. Oğuz Şahin, who died after falling ill on Nov. 2 near the Alparslan Border Outpost in Van province’s Çaldıran district.
