Four people have been injured in a car bomb explosion in Kyiv's Solomyansky district on Wednesday night, one of them has died on the way to hospital, head of the Kyiv police's press service Oksana Blyschyk has said.

"According to preliminary reports, four injured people have been taken away from the scene in ambulances. Doctors have informed that one of the victims has died on the way to hospital. The condition of the remaining injured persons is unknown," she wrote on Facebook on Wednesday night in an update.

As Interfax-Ukraine has learnt from a source, one of the victims was Member of Parliament from the Radical Party Ihor Mosiychuk.

"Ihor Volodymyrovych was on air on the Espresso TV channel. He was leaving the building together with his body guard, as the car that was parked near the building's exit exploded," Mosiychuk's press secretary Anna Senik told TV Channel 112.

She said Mosiychuk had been taken to hospital where he was given medical assistance. "It is not known what kind of injuries he has got. I know that he, his face, was heavily stained with blood," Senik said.

She also knew nothing about the condition of the body guard who was next to Mosiychuk amid the bomb explosion.

Senik also reported that Mosiychuk had repeatedly received death threats. "There were a lot of death threats, including from [Head of the Chechen Republic] Ramzan Kadyrov, and in due time the Security Service of Ukraine provided him with guards ... and as far as I know nobody has cancelled these threats, and there is still a threat to his life."

At the same time, MP from the Radical Party parliamentary faction Dmytro Linko wrote on his Facebook page that Mosiychuk was undergoing surgery.

"Ihor's surgery is under way. He has got a lot of shrapnel wounds. His assistant is also severely wounded," he said
