STORY: Erdogan added that Turkey's air operations against a Kurdish militia in northern Syria were only the beginning and it would launch a land operation when convenient after an escalation in retaliatory strikes.
Ankara launched air operations at the weekend in retaliation for an Istanbul bomb attack a week earlier that killed six people, and which it blamed on the YPG. Nobody has claimed responsibility and the PKK and YPG have denied involvement.
Turkish Defense Minister Hulusi Akar said the army had hit 471 targets in Syria and Iraq since the weekend in what he said was Turkey's biggest air operation of recent times.
The YPG-led Syrian Democratic Forces (SDF) said the Turkish military attacked north and eastern Syria for a third day on Tuesday (November 22), using aircraft, drones and heavy artillery, with civilian infrastructure including hospitals and a school among the targets hit.
The United States has allied with the SDF in the fight against Islamic State in Syria, causing a deep rift with Turkey.
