Russian investigators have rejected a request by jailed Ukrainian pilot Nadia Savchenko to be tried by a jury.
Savchenko lawyer Nikolai Polozov said on July 6 that he was informed via phone that "all the petitions have been denied and the case was transferred to the prosecutor's office."
Savchenko's defense team said last week the preliminary hearing may be held in late July or early August.
Savchenko, who has been jailed in Russia since July 2014, says she was illegally brought into Russia after being abducted by Russian-backed separatists in eastern Ukraine.
She is charged with complicity in the killing of two Russian journalists who died while covering the Ukraine conflict, as well as illegal border crossing.
Savchenko denies the charges and says Russia has no right to detain her.
Western countries and Kyiv have repeatedly called for her immediate release.
