The body of journalist Jamal Khashoggi was "dissolved" after he was murdered and dismembered in the Saudi consulate in Istanbul a month ago, an advisor to Turkish President Recep Tayyip Erdogan said Friday.

The claim echoed what a Turkish official had told the Washington Post that authorities are investigating a theory the body was destroyed in acid. "We now see that it wasn't just cut up, they got rid of the body by dissolving it," Yasin Aktay, an advisor to Erdogan and official in Turkey's ruling party, told the Hurriyet newspaper on Friday. "According to the latest information we have, the reason they cut up the body is it was easier to dissolve it," Aktay said.
