Russia and Kazakhstan have sought to temper speculation about the cause of the Azerbaijan Airlines plane crash, with the Kremlin urging people to wait for the results of the investigation, writes the Guardian's European community affairs correspondent Ashifa Kassam and Pjotr Sauer, the Russia affairs correspondent.
