The questioning has been appointed for Tuesday, March 13.
The Security Service of Ukraine, also known as SBU, has summoned Ukrainian MP Nadiia Savchenko for questioning in the case of Volodymyr Ruban, a Ukrainian hostage swap negotiator who was recently busted with a truck-load of weapons and arms when trying to cross into a government-controlled territory from the militant-occupied area and subsequently charged with plotting a terrorist act against the country's top officials in Kyiv.
The report on the upcoming interrogation was initially posted on Facebook by Deputy Minister for temporarily occupied territories and IDPs George Tuka and later confirmed by Prosecutor General Yuriy Lutsenko.
According to earlier reports, Savchenko's ally and aide Oleh Mezentsev is mentioned in a suspicion notice handed down to Volodymyr Ruban.
Savchenko was spotted attending a court hearing where a preventive measure was selected for the high-profile detainee.

He noted that Savchenko was not a member of the official delegation, but at the same time had all grounds for participation in such an event.
"I would now like to turn to MP Savchenko: if she is really that courageous and honest as she claims on constant TV shows, tomorrow she must report to the Security Service of Ukraine," the Prosecutor General said.
According to Lutsenko, cooperation with the investigation would be very important for both Savchenko and the country.
