Hundreds of Turkey-backed rebels have also been killed and wounded during the military showdown in Afrin, the statement noted.
A total of 899 PKK/KCK/PYD-YPG and Daesh terrorists have been "neutralized" since the beginning of Operation Olive Branch in Syria's Afrin region on January 20, according to the Turkish General Staff on Saturday.
Turkey views the YPG (People's Protection Units) as a terrorist group and an extension of the banned Kurdistan Workers' Party (PKK), which has fought for Kurdish autonomy in south-eastern Turkey for three decades.
The Turkish General Staff said in a statement that the armed forces had destroyed 15 terrorist targets and neutralised 74 terrorists in Friday night airstrikes, reported Anadolu Agency.
Earlier on Saturday, the Turkish General Staff said one soldier had been martyred and another injured in Sheikh Haruz, where the terrorist group targeted a Turkish army tank. The seventh one was killed in a YPG attack on the border, without giving further details.
Turkey says it has killed some 900 Kurdish fighters, but this can not be independently verified.
In Strasbourg, Kurdish protesters carried banners reading "Erdogan assassin" and "defend Afrin", and shouted slogans such as "silence kills" outside the Council of Europe offices.
The Turkish forces also gained control of Mount Barsia.
The Human Rights Watch report comes amid rising tensions along the Turkey-Syria border as Turkey's military has moved into northern Syria.
"As fighting in Idlib and Afrin displaces thousands more", Fakih said, "the number of Syrians trapped along the border willing to risk their lives to reach Turkey is only likely to increase".
