Turkey says Khashoggi, who wrote for The Washington Post columnist and often criticized the crown prince, was killed by a 15-member assassination squad sent from Riyadh.
Luggage carried by a 15-member Saudi team dispatched to Istanbul included scissors, defibrillators and syringes that may have been used against journalist Jamal Khashoggi, who was murdered in the Saudi consulate, a pro-government Turkish daily said Tuesday.
Erdogan said he does "not believe for a second" that the crown prince's father King Salman ordered the hit. "We are waiting patiently", Erdogan said, adding that the perpetrators of the killing were among 18 suspects detained in Saudi Arabia.
Shortly after Khashoggi's disappearance, Turkish authorities reported that Khashoggi had been killed and that they had a recording to prove this.
Recordings of the October 2 operation, carried out by a 15-man hit squad inside Istanbul's Saudi Consulate, have been shared with Western intelligence officials.
Mr Altun said Ankara had shared evidence linked to the murder with officials from a large number of countries and that France was "no exception".
"If the Turkish president has information to give to us, he must give it to us". However, he did not elaborate on what was in the recordings.
Mr Trudeau has faced calls to cancel a $13bn (£10bn) arms deal with Saudi Arabia for tanks and armoured fighting vehicles built by an Ontario-based unit of the United States firm General Dynamics.
On Monday, U.K. Foreign Secretary Jeremy Hunt became the first British minister to visit Saudi Arabia since the October 2 killing.
Sidestepping a question on whether the recordings could change Ottawa's relationship with Riyadh and have consequences, Trudeau said he was continuing to talk with allies about the investigation and accountability for those behind the murder.
Saudi Arabia has said Khashoggi was murdered in an unauthorised operation.
The prime minister said he has not personally heard the recordings Turkey provided to Saudi Arabia along with allies such as the US and Britain in recent days, though he said he has been made aware of their contents.
Western diplomats and Turkish officials say that it would be hard to carry out such an operation without the approval of Mohammed, the kingdom's de facto ruler.
Khashoggi had criticized Saudi Arabia for not allowing open discussion and dissent; just before his death, he also discounted claims that the crown prince could be a force for reform.
A source at Turkish attorney general's office Saudi authorities had used acid and other chemicals to dispose of the slain journalist's body.
But last month, in an apparent shift to ease global outrage, they acknowledged Turkish evidence indicated that the killing was premeditated.
