Investigators "have obtained unprecedented and unquestionable proof of the guilt" of four Ukrainians accused of this year's bombings in the Ukrainian cities of Dnipropetrovsk, Kharkiv and Zaporizhia, the chief investigator of the Ukrainian Security Service (SBU) said on Thursday, Aug. 30.
The accused made and tested their bombs in the three cities in
2010-2012, Ivan Derevyanko, the Security Service’s chief investigator,
told a news conference in Kyiv.
After their final attack in Dnipropetrovsk, the bombers sent letters
to government agencies and media outlets demanding $4.5 million and were
arrested in a sting operation in which the SBU transferred a sum of
money to bank accounts indicated by them, Derevyanko said.
Evidence collected by the SBU included a video tape showing the
accused planting a bomb and expert assessments that they had used some
of the items seized from them in making their bombs.
