Sources at the attorney-general's office "say these samples provide further evidence of the conclusion that Jamal Khashoggi was killed inside the consulate building", an Al Jazeera correspondent said, reporting from Istanbul.

President Donald Trump has responded equivocally, both promising harsh action if the royal court is implicated in Khashoggi's disappearance and saying he'd be reluctant to cancel multibillion-dollar arms sales to the kingdom.
The existence of audio evidence that Mr Khashoggi - a critic of Saudi leaders - was murdered was revealed by Turkish investigators early on in their inquiries. It was the second-such extraordinary search of land considered under worldwide law to be Saudi sovereign soil after Turkish police searched the consulate through the early morning on Tuesday.
