"We do not recognize semi-Autonomous areas self-government on the territory of Syria," Kirby said in response to a journalist's question about the creation of a Kurdish Federal region in the North of the country.

"We want to see Syria United and whole country under the control of the government, led by Bashar al-Assad, which would meet the requests of the Syrian people. A holistic, unified, secular Syria — that's our goal," said Kirby, adding that other countries share this approach.

Syrian Kurds announced the creation of a Federal region in the North of the country on Thursday. Against this decision was made by the most active forces in the region.

The Syrian government has already stated that this decision has no legal force. Turkish authorities also said they oppose a unilateral decision on federalization.

Deputy foreign Minister of Russia Mikhail Bogdanov told the Interfax news Agency that Moscow also supports the decision.
