ANKARA, Turkey — Turkish forces swept into Syria overnight to rescue about 40 soldiers who had been surrounded for months by ISIS militants while guarding the tomb of a revered Turkish figure.
The Syrian government described the operation as act of "flagrant aggression" and said it would hold Ankara responsible for its repercussions.
The operation, which involved tanks, drones and reconnaissance planes as well as several hundred ground troops, was the first such incursion by Turkish troops into Syria since the start of the civil war there nearly four years ago.
The military said no clashes took place during the operation although one soldier had been killed in an accident.
The 38 soldiers who had been guarding the tomb of Suleyman Shah, grandfather of the founder of the Ottoman Empire, were brought safely home. The tomb, which is on a site within Syria that Ankara considers sovereign territory as agreed in a 1921 treaty, was relocated.
