Biden ends Turkey visit
US Vice President Joe Biden on Sunday wrapped up a key visit to Turkey without a breakthrough on military co-operation in the Syrian crisis but with officials confident the talks brought their positions closer.
During his three-day trip to Istanbul, Biden held several hours of talks with both Turkish President Recep Tayyip Erdogan and Prime Minister Ahmet Davutoglu on the crises created by the capture by Islamic State of Iraq and Syria (ISIS) jihadists of swathes of Iraq and Syria.
