The United Nations' human rights office has said it could not assess the fairness of a trial taking place in Saudi Arabia into the killing of journalist Jamal Khashoggi, adding that it was "not sufficient". "Ultimately, it's impossible to view any accountability that ignores the role of Crown Prince Mohammad bin Salman as legitimate or credible".
Rights groups have called for an independent investigation into Khashoggi's killing.
The Saudi state new agency SPA reported the court had approved a request from the 11 who asked for more time to prepare their defence.
There was no immediate reaction to Thursday´s trial from Ankara, which has sought the extradition of the suspects in Saudi custody to stand trial in Turkey.
Turkish media did publish a list of 15 men who they say formed the hit squad, taken from documents they showed as they passed through passport control.
The United Nations High Commissioner for Human Rights (OHCHR) says it can not assess the fairness of a trial underway in Saudi Arabia over the killing of dissident journalist Jamal Khashoggi, emphasizing that in any case it is "not sufficient".
His body is believed to have been dismembered, removed from the building and handed over to an unidentified 'local cooperator'.

Turkish officials told MEE this week that Saudi authorities have themselves continued to provide inadequate information on the case and were obstructing Turkey's investigation.
"No response has been received to date and the Public Prosecutor's Office is still waiting for an answer", the prosecutor's statement read.
The kingdom initially denied Khashoggi was killed, but changed its story and acknowledged his slaying weeks later.
That has not stopped widespread global criticism against the kingdom.
For decades he was close to the Saudi royal family and also served as an adviser to the government. Riyadh, however, insists that the killing was a rogue operation.
In his last column, he criticised Saudi involvement in war in Yemen.
It is no surprise that the kingdom would seek to execute those accused in Khashoggi's slaying. France and Canada have also sanctioned Saudi Arabian nationals. It regularly beheads those condemned to death and previous year said it "crucified" a Myanmar man, an execution in which the condemned is usually beheaded and then the body put on display, arms outstretched as if crucified.
