Turkey agreed on Thursday to pause its offensive in Syria for five days to let Kurdish forces withdraw from a “safe zone” Ankara had sought to capture.
"The so-called ceasefire is not what we expected. In fact, it's not a ceasefire, it's a demand of capitulation of the Kurds," Tusk told journalists in Brussels.
"We have to reiterate our call to Turkey to put a permanent end to its military action immediately and withdraw its forces and respect the international humanitarian law."
