Turkish Prime Minister Recep Tayyip Erdogan said he ceased direct phone contact with US President Barack Obama once the US backed away from use of military force against Syria last fall.

Erdogan, a supporter of rebel fighters opposed to Syrian President Bashar Assad’s government, was upset, he said, that the United States did not follow through with military action against Damascus amid the fierce civil war there.

"In the past, I was calling him (Obama) directly. Because I can't get the expected results on Syria, our foreign ministers are now talking to each other," Erdogan said Monday in an interview with the pro-government ATV channel.
