US President Barack Obama has urged Turkey and Russia to remove the row, a week after Turkish jets shot down a Russian warplane.
After talks with Turkey’s Recep Tayyip Erdogan in Paris, Mr Obama reaffirmed US support for “Turkey’s right to defend itself and its airspace”.
But he stressed that Russia and Turkey should “de-escalate” their dispute.
“We all have a common enemy,” Mr Obama said, referring to the so-called Islamic State (IS) group.
“I want to make sure that we focus on that threat,” he said.”Turkey is a Nato ally,” he added. “And we’re very much committed to Turkey’s security and its sovereignty. We discussed how Turkey and Russia can work together to de-escalate tensions and find a diplomatic path to resolve this issue.”
Mr Erdogan also spoke to reporters after Tuesday’s meeting. He said his government wanted to reduce tensions and was “determined to keep up the fight” against IS.
Mr Obama and Mr Erdogan are among 150 leaders attending climate talks in Paris.
