One member of the Free Syrian Army (FSA) has been killed, while there were no casualties among the Turkish military.
Ankara announced on early Wednesday that Turkish forces, backed by US-led coalition aircraft, had begun a military operation dubbed "Euphrates Shield" to clear the Syrian border town of Jarablus of Daesh terrorists.
"Free Syrian Army takes control of Jarabulus; no casualties in Turkish army, 1 FSA member killed," the Anadolu news service said on its Twitter account.
The Dogan service reported earlier that FSA fighters seized all government buildings in the northern Syrian town on the western bank of the Euphrates.
Syrian Kurds and Damascus accuse Ankara of violating the territorial integrity of the Arab republic.
