"They give support to terrorist groups including Daesh," Erdogan said.
Saying that the US have accused Turkey of supporting Daesh, speaking at a press conference on Tuesday the Turkish leader blamed the US-led coalition for assisting terrorists themselves.
Apart from Daesh, he also mentioned Kurdish People's Protection Units in northern Syria (YPG) and Democratic Union Party (PYD) as groups supported by the coalition.
"We have confirmed evidence, with pictures, photos and videos," he added.
Erdogan has also called on Saudi Arabia and Qatar to join Russia, Turkey and Iran in peace talks on Syria. On Tuesday, the Turkish leader said officials of these Persian Gulf states should be included in the talks of foreign ministers in Kazakhstan next month, as their countries had "shown goodwill and given support'' to Syria, RT reported.
However, the Turkish president stressed that Ankara itself would not take part should Syrian Kurdish groups - whom he called "terrorist organizations" - be invited to take part in the meeting.
Commenting on Ankara's accusations, US State Department spokesman Mark Toner said Erdogan's claims were "ludicrous."
