A court in Moscow on May 6 extended the pretrial detention of Ukrainian pilot and parliament member Nadia Savchenko until June 30.

The announcement was made on Twitter by her lawyer, Nikolai Polozov..

The hearing came a day after Savchenko's lawyer announced that Russian authorities have extended their preliminary inquiry into Savchenko’s case until November 13.

Savchenko has been jailed in Russia since July, when she says she was illegally brought into the country after being abducted by Russian-backed separatists in eastern Ukraine.

She is charged with complicity in the killing of two Russian journalists who died in the conflict in eastern Ukraine, as well as illegal border crossing.

She denies guilt and conducted a hunger strike for more than 80 days to protest her incarceration.

The United States said on May 5 that it is concerned over the "callous and outrageous" treatment of Savchenko by Russian authorities, and called for her immediate release.
