Сensor.NET reports referring to the presidential press service.
"Meeting with the leadership of security forces, President Petro Poroshenko emphasized that a terrible crime has been committed today, which claimed the life of patriot and talented journalist Pavel Sheremet, for whom Ukraine was a second homeland. He extended sympathies to the loved ones and friends of the deceased," the statement notes.
"It is a matter of honor to take all measures to solve this crime as soon as possible," Poroshenko remarked.
He stressed that the probe should be as transparent as possible.
"Do not exclude any version," the head of state said to the leadership of law enforcement agencies.
The president also recalled a difficult situation at the front and a record number of killed soldiers.
"We shouldn't forget that the country is defending itself against the Russian aggressor and the best sons of Ukraine sacrifice their lives at the front line. We'll not let anyone open a second front inside the country."
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 murder. 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 is set to establish an inter-agency working group to investigate the death of Sheremet.
According to witnesses, the explosion occurred when Sheremet stopped at an exit to a main road. They note high detonation velocity.
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.
The tragic death of the journalist provoked strong public outcry. The chief editor of Ukrainska Pravda Sevhil Musaieva-Borovyk said: "This is a blow to entire Ukrainian journalism." OSCE called for bringing organizers and perpetrators to justice. Lithuanian Foreign Minister Linkevičius called for a thorough investigation. Ukrainian President Poroshenko expressed his sympathies to the family and friends of Sheremet. Verkhovna Rada Speaker Parubii called for an immediate investigation. Similarly, an urgent and effective probe was ordered by Prime Minister Hroisman. NSDC Secretary Turchynov also expressed his condolences. President Poroshenko said international experts from FBI will be involved in investigation of the killing.
Sheremet will be buried in Minsk.
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.
Over the past five years, Sheremet has lived in Kyiv, worked for Ukrainska Pravda and was a host at Vesti radio.
