Input: Consider Input: Barak is the first Israeli official to visit Turkey since the diplomatic feud that erupted Monday after Israel's deputy foreign minister  Danny Ayalon  summoned Turkish Ambassador Ahmet Oguz Celikkol to complain about a TV show. The ambassador was forced to sit on a low sofa without a handshake  while Ayalon explained to local TV stations that the humiliation was intentional. Outraged  Turkey threatened to recall the ambassador  forcing Ayalon to apologize.
 Barak on Sunday met with Turkey's Foreign Minister Ahmet Davutoglu to discuss the latest crisis. He is also scheduled to meet Turkish Defense Minister Vecdi Gonul later Sunday.
 Barak and his fellow Labor Party member  Minister Binyamin Ben Eliezer  have significantly warmer relations with Turkey than Ayalon and Foreign Minister Avigdor Lieberman's ultra-nationalist party.
 Upon his arrival in Turkey  Barak was greeted warmly at the airport by a Turkish admiral. His first stop was at the mausoleum of modern and secular Turkey's founder  Mustafa Kemal Ataturk  whom Barak praised as an inspiration in making the region "one of peace and security."

Input: Consider Input: Chloe Ayling  who called the ordeal a âterrifying experienceâ during a British television interview in August  recently uploaded a fully nude image to her Instagram account.  Ayling   however  is turned from the camera  and not all of her body is visible in the black and white snap.
 Ayling  says  she  was drugged and held hostage by a group that called  itself  Black Death after being lured to Milan for a fake photo shoot in July.  She  said the kidnappers planned to auction  her  on the dark web to the highest bidder -- unless  she  paid $355 000 for  her  freedom.
George Hepburne Scott  the lawyer for 36-year-old suspect Michal Herba  has argued in court that the case might have been made up as part of an elaborate publicity stunt to boost  Ayling 's career.
The 20-year-old model has maintained  her  kidnapping was real  saying on Britainâs âThis Morningâ in August  she  feared  she  would be killed and prayed for a ânon-painful death.â
 Ayling  described being drugged  stuffed into a suitcase  transported to an isolated farmhouse and held for almost a week by  her  captors. The kidnappers allegedly threatened to advertise  her  as a sex slave or hold  her  for ransom.
 Ayling  has also announced  she  will be writing a book to "expose every little detail for the first time." The book  titled "Six Days " is expected to be released in Spring 2018.
