Turkey has withdrawn from a two-day summit on Libya that is being held in Italy, expressing “deep disappointment,” Turkish Vice-President Fuat Oktay said on Tuesday, objecting to what he said was Ankara’s exclusion from some of the talks. “Any meeting which excludes Turkey would prove to be counter-productive for the solution to this problem,” Oktay said, according to Reuters. He was speaking from Palermo, where the summit is taking place. The participants are discussing a UN peace plan to stabilize the North African country, which has been in turmoil since 2011.
