"The explanations offered to date lack consistency and credibility," Canadian Foreign Minister Chrystia Freeland said in a statement
Saudi Arabia faced a growing chorus of incredulity Sunday over its belated explanation of how critic Jamal Khashoggi died inside its Istanbul consulate, as world powers demanded answers and the whereabouts of his body.
After a fortnight of denials, Saudi authorities admitted on Saturday that the Washington Post columnist was killed after entering the consulate on October 2, a disappearance that sparked outrage and plunged the Gulf kingdom into a spiralling international crisis.
Turkish officials have accused Riyadh of carrying out a state-sponsored killing and dismembering the body, with pro-government media in Turkey reporting the existence of video and audio evidence to back those claims.
Police have searched a forest in Istanbul where they believe his body may have been disposed of.
After initially saying Khashoggi left the consulate unharmed, and then that they were investigating his disappearance, Saudi authorities backtracked and admitted the 60-year-old was killed in a "brawl" with officials inside the consulate.
But that narrative -- combined with the absence of Khashoggi's body -- quickly drew scepticism and scorn from many, including staunch allies.
Ankara vowed to reveal all the details of a two-week inquiry as US President Donald Trump said he was unsatisfied with Saudi Arabia's response to the columnist's death while the EU, Germany, France, Britain, Australia, Canada and the UN also demanded greater clarity.
The controversy has put the kingdom -- for decades a key ally in Western efforts to contain Iran -- under unprecedented pressure.
It has also evolved into a major crisis for Crown Prince Mohammed bin Salman, a Trump administration favourite widely known as MBS, whose image as a modernising Arab reformer has been gravely undermined.
Canada is among the latest countries to question Riyadh's version of events.
"The explanations offered to date lack consistency and credibility," Canadian Foreign Minister Chrystia Freeland said in a statement Saturday.
Senior Republican senator Marco Rubio was more stark in his assessment.
"Saudi Arabia's changing stories on #KhashoggiMurder is getting old. The latest one about a fist fight gone bad is bizarre," he tweeted, renewing his call for sanctions against those responsible.
Ankara said it had a "debt of honour" to reveal what happened.
"We are not accusing anyone in advance but we don't accept anything to remain covered (up)," said ruling Justice and Development Party spokesman Omer Celik.
French Foreign Minister Jean-Yves Le Drian said many questions remained unanswered while German Chancellor Angela Merkel urged transparency, adding that "available reports on what happened in the Istanbul consulate are insufficient."
"This cannot stand. This will not do," Australian Prime Minister Scott Morrison added on Sunday.
The EU's top diplomat Federica Mogherini and UN chief Antonio Guterres both called for a proper investigation and for the perpetrators to be held to account.
Trump initially said he found the explanation credible, but later expressed more scepticism -- although he warned against scrapping a multibillion-dollar arms deal with the conservative kingdom.
"No, I am not satisfied until we find the answer," he told reporters. "It was a big first step. It was a good first step. But I want to get to the answer."
Saudi Arabia's Gulf ally, the United Arab Emirates, welcomed the Saudi disclosures, as did Egypt.
