President Recep Tayyip Erdogan yesterday renewed Turkey’s threat to launch an “air and ground” operation in Syria against a Kurdish militia viewed as terrorists by Ankara.

The president previously said that Turkey’s patience was wearing thin after Turkish and American officials agreed in August to establish a buffer zone in northern Syria.

“We’ve made our preparations, completed our operation plans, given the necessary instructions,” Erdogan said during a televised speech, adding that the offensive could start “as soon as today, tomorrow”.

“We will conduct this (operation) on the ground and in the air,” he added, saying it would be east of the Euphrates river.

Erdogan has repeatedly threatened to launch a cross-border offensive and recently suggested that progress on the zone with the US was not developing as Ankara wanted.
