Erdogan also took the opportunity to call on world powers to stop supporting "terrorist organizations," including the Kurdish People's Protection Unit (YPG). The US calls the YPG a "moderate rebel group" and has given it military support and arms through the Syrian Democratic Forces alliance fighting ISIS militants.
"Some say ... we do not recognize the YPG as a terrorist organization because they fight against Daesh," Erdogan said, using the Arabic acronym for ISIS.
He pointed out that Jabhat Fatah al-Sham, the militant group formerly known as Jabat Al-Nusra, was also fighting ISIS and was internationally considered a terrorist organization.
"They fight against Daesh. Just because a terrorist fights another terrorist, can you call them a good terrorist? At least that's what we are seeing in Syria and Iraq," he said.
His logic is lacking here; one militant group fighting ISIL does not mean someone else fighting them is ALSO a militant organization. the YPG is one of the best hopes for moderation in Northern Syria, from what I can tell.,
