Turkish President Recep Tayyip Erdogan put US President Donald Trump’s letter “in the bin”, the BBC has been told.
In the letter dated 9 October, and sent after US troops were pulled out of Syria, Mr Trump told Mr Erdogan: “Don’t be a tough guy. Don’t be a fool!”

US Vice President Mike Pence is now in Ankara to push for a ceasefire.
