In a statement carried by Turkey’s NTV television on Tuesday, the army said the casualties came after a Daesh rocket attack on two of its tanks south of the town of al-Ra’i, near the Turkish border.
The fatalities were the first of Turkey's recent incursion into Syria to be blamed on Daesh.
The Turkish television showed pictures of military helicopters flying across the Turkish-Syrian border to take the wounded to Turkey for treatment.
Separately, two pro-Turkey Syria militants were killed and two others sustained injuries in clashes in the same region, the Turkish army statement added.
On August 24, Turkish special forces, tanks and jets backed by planes from the US-led coalition launched their first coordinated offensive in Syria. Damascus denounced the intervention as a breach of its sovereignty.
Turkish President Recep Tayyip Erdogan said the operation, dubbed "Euphrates Shield," was aimed at “terror groups” such as Daesh and the Democratic Union Party (PYD), a US-backed Kurdish group based in Syria.
Hours after the beginning of the offensive, Turkish-backed militants seized the city of Jarablus, with Ankara saying that it wanted to establish a safe zone in the 98-kilometer (61-mile) area stretching from Jarablus to the city of A'zaz; Press TV reported.
