According to media reports, the ground phase of the Turkish operation against Kurdish fighters and Daesh positions in northwest Syria started early on Sunday after Turkish President Recep Tayyip Erdogan ignored Washington's calls to avoid attacking Afrin.
Earlier, Turkish Prime Minister Binali Yildirim warned of a possible ground operation against Kurdish forces in Syria's northern Afrin district.
"Today our air force hit most of the designated targets. Tomorrow, depending on the circumstances, our ground forces will carry out the necessary work. They will move together with the Free Syria Army," Yildirim told reporters on Saturday.
"The operation is not against our Turkmen, Kurdish or Arab brothers living there [in Afrin], but against the terrorist groups. It has been launched with a respect for Syria's territorial integrity, sovereignty and political unity, and will be carried out taking these principles into account. After the operation reaches the assigned tasks, Turkey will leave Afrin," Bozdag said, as quoted by Ihlas News Agency.

Meanwhile, Syria fired three rockets early on Sunday targeting the Turkish border province of Kilis and lightly injuring one person, media reported citing local governor. According to Anadolu news agency, the rockets hit several locations in the provincial capital of Kilis and damaged some buildings in the area.
The military operation has already been condemned by Damascus and the Syrian Foreign Ministry claimed that Operation Olive Branch was a violation of Syrian sovereignty.
Turkey is claiming self-defense under international law. According to the statement of Turkish senior military officials, operation Olive Branch is aimed at eliminating Kurdish YPG militants along with the Daesh terrorist group.
The operation started at 14:00 GMT on Saturday and over 70 Turkish warplanes conducted airstrikes in seven districts of Afrin, where 108 targets were hit.
