The National Police of Ukraine has said the explosive device that killed journalist Pavel Sheremet contained an anti-personnel mine.

"Taking this into account it is possible to establish the contents of the explosive device. In addition, the blueprint for the location of the device and its location in the automobile," said the head of the National Police's investigation department Oleksandr Vakulenko at a press conference in Kyiv on Wednesday.

Vakulenko said the bomb contained a MON-50 anti-personnel mine, two firing pins and an electric detonator.

Several experiments using a car and copies of the explosive device bear out the preliminary conclusions of the investigation. Vakulenko said nine of the 16 forensic analyses have been carried out.

Well-known Belarusian journalist Pavel Sheremet was killed on July 20, 2016 in the center of Kyiv when his automobile exploded. The car belonged to his companion Olena Prytula, the co-founder of the Kyiv-based Ukrayinska Pravda news website. Police have said the main motive for Sheremet's murder was his journalist activities.

Ukrainian prosecutors have said several individuals are suspects in their investigation. They say the perpetrator did not act alone.
