“Our forces are present all over Afrin’s geography. These forces will strike the positions of the Turkish enemy and its mercenaries at every opportunity,” Othman Sheikh Issa, co-chair of the Afrin executive council, said in a televised statement.

“Our forces all over Afrin will become a constant nightmare for them.”

Turkish forces and their Syrian rebel allies swept into the northwestern Syrian town of Afrin on Sunday, raising their flags in the town centre and declaring full control after an eight-week campaign to drive out fighters from the Kurdish YPG militia.

Issa said Kurdish fighters had shown “unparalleled steadfastness and resistance” in the fight, but that Kurdish authorities had decided to evacuate civilians from Afrin “to avoid a worse humanitarian catastrophe”.
