MOSCOW, October 28 (RAPSI) – Ukrainian pilot Nadezhda Savchenko, who has been charged with complicity in the murder of Russian journalists, may also be charged with illegally crossing the border, RIA Novosti announced on Tuesday, citing the pilot’s lawyer Ilya Novikov.

Novikov said his client’s arrest had been extended until February 13. The court also said the investigators had sent a request to the Federal Security Service on bringing new charges against Savchenko. Crimes under the new article are punishable by up to three years in prison.

The investigators were not available for comment. The court hearing was held behind closed doors.

Savchenko, 33, called in artillery fire via radio. She was seized by anti-Maidan fighters in June but, according to the independence supporters in the Lugansk area, managed to escape. Later she was detained in Russia, which she allegedly entered as a refugee, and was charged with complicity in the murder of Russian journalists during the shelling of the self-defense forces in the contested Ukrainian region of Luhansk.

Vesti correspondent Igor Kornelyuk and sound engineer Anton Voloshin were killed on June 17 in a mortar attack in the vicinity of Metallist and Mirny, small towns near Lugansk in eastern Ukraine. Both journalists were buried in Moscow.

Savchenko denies the allegations and insists she has no relation to the death of the journalists. President Petro Poroshenko of Ukraine said he would demand Savchenko’s immediate release and return to Ukraine.
