No significant progress was made in the investigation of the murder of journalist Pavel Sheremet, the Ukrainian National Police Chief Khatia Dekanoidze said.

"You have no idea what large-scale work our investigators conducted. I would like not to talk about numbers yet, but they have already questioned several hundred people, watched a large amount of footage, and if we make a breakthrough, you will know it. Unfortunately I cannot say that yet," she told reporters at a briefing in Kyiv on Friday.

Well-known journalist Sheremet was killed in an explosion of a car in the downtown Kyiv on July 20, 2016. The explosion occurred at 07.45 a.m., when Sheremet was driving the car, which, according to the media, belonged to the Ukrayinska Pravda head Olena Prytula. She was not in the car at the moment.

Ukrainian Prosecutor General Yuriy Lutsenko said that the key theory of the murder is revenge due to the journalist's professional activities.
