It's been Turkey's deadliest day since it launched an offensive against Kurdish militias inside northern Syria over two weeks ago.
Five soldiers died when a Turkish tank was hit by YPG militia while two solders were killed elsewhere.
Violence has escalated in northern Syria in recent days as Turkish forces target the city of Afrin and threatened to push further east toward the border with Iraq.
Since the start of the operation dozens of rockets have hit the Turkish border towns of Reyhanli and Kilis where a refugee camp is home to thousands of Syrians .
One refugee says he fled to the city after heavy bombing in Syria and escaped to Turkey where once again he is under fire. He says he will stay in Kilis until it is safe to return home.
The bombings have also targeted people's houses and public utilities in nearby villages like Jandarais.
Meanwhile in Paris, thousands of protesters marched to support Turkey's Kurds and protest the Turkish military incursion into Afrin.
The demonstrators urged French and other Western authorities to take a tougher stand against Turkey.
