He said at a press conference on Monday, Censor.NET reports.
"The attempt on my life, prevented by the Security Service of Ukraine, is just one of the activities by a Russian-based terrorist subversive center instructed to engage only the citizens of Ukraine, often with a criminal record and hatred for our country and brainwashed by Russian propaganda, to commit crimes in the territory of our country," he said.
"At the moment, judging by the pattern and preparation of the terrorist attack on my life, the investigators believe with 99.9 percent certainty that the murder of prominent journalist Pavel Sheremet in July 2016 was orchestrated by the same terrorist subversive center based in the territory of the Russian Federation," the lawmaker said.
Earlier, Vasyl Hrytsak, head of Ukraine's Security Service, unveiled the details of the assassination attempt on Herashchenko at a press briefing.
As reported, prominent journalist Pavel Sheremet was killed in a car bombing in downtown Kyiv on Wednesday morning, July 20. The incident is preliminary qualified as assassination. Then-National Police chief Khatia Dekanoidze said the investigation into the killing of Sheremet would be a matter of honor for her. Kyiv prosecutor Hovda took the probe under personal control. The Information Policy Ministry planned to establish an inter-agency working group to investigate the death of Sheremet. Investigators followed up six versions in Sheremet's killing.
According to witnesses, the explosion occurred when Sheremet stopped at an exit to a main road. They noted high detonation velocity.
The U.S. Embassy in Ukraine extended condolences to Pavel Sheremet's family, friends and colleagues, hoping for a thorough investigation into his death.
Prosecutor General Lutsenko commented on the tragedy: "The death of Sheremet was due to an explosive device. It's a murder." Later, the Interior Ministry added a homemade shell-less explosive device was used, its power equivalent to 600 grams of TNT.
President Poroshenko met with the heads of Ukraine's law enforcement agencies, after which a special investigative group was set up under the leadership of Dekanoidze. Ukraine has invited FBI and Europol experts to help in the probe. The Security Service considered the destabilization of the situation in Ukraine as a motive for Sheremet's murder. Meanwhile, Poroshenko asked for a transparent and prompt investigation: "Do not exclude any version. We'll not let anyone open a second front inside the country."
Originally from Minsk, Sheremet was particularly critical of Belarusian president Alexander Lukashenko's crackdown on dissent.
In 1997, the journalist was arrested while reporting about smuggling across the Belarus-Lithuanian border and sentenced to two years in prison - a move widely viewed as politically motivated. Amnesty International declared him prisoner of conscience.
In 1999, Sheremet was presented with the Committee to Protect Journalists' International Press Freedom Award. In 2002, he was presented with the Organisation for Security and Cooperation in Europe's Prize for Journalism and Democracy.
For five years prior to the murder, Sheremet had lived in Kyiv, worked for Ukrainska Pravda and been a host at Vesti radio.
