UPDATE 1-Turkish police starts probe of 'well' in Saudi consulate in Istanbul

Turkish police are investigating water samples taken from a well at the Saudi consulate in Istanbul as part of an investigation into the killing of journalist Jamal Khashoggi, broadcaster CNN Turk said on Thursday.

Turkish authorities on Wednesday were granted permission by Saudi officials to carry out inspections at the well after being initially denied access.

After weeks of conflicting reports on Khashoggi's fate, Saudi Arabia at the weekend said the journalist had been killed in a botched interrogation at the consulate, prompting an international outcry.
