A colonel in Ukraine's military intelligence was killed by a auto bomb in central Kiev today, the defence ministry said, describing the incident as a "terrorist act".
Police said the explosion occurred early morning while the vehicle was moving.
According to the Ukrainian Interior Ministry, the incident, which occurred at about 8:00 a.m. local time (0500 GMT), also left two passers-by slightly injured by shrapnel.
Shevchenko said that judging by initial indications it appeared "obvious" that the blast was caused by an explosive device, adding that investigators were probing it as terrorism.
The blast is the latest deadly incident to rock the city, as crisis-hit Ukraine battles a bloody Russian-backed insurgency in its eastern regions.
T online newspaper editor-in-chief Yuriy Butusov said that Shapoval headed the special reserve department of the Ukrainian Defense Ministry's Chief Intelligence Directorate.
"The national police, rescuers, as well as explosives and forensic experts are working at the scene", the Defense Ministry said.
Reports said that the incident is the second one in four days.
In March, former Russian MP Denis Voronenkov, a critic of President Vladimir Putin, was shot dead outside a hotel in the capital.
The last major incident in Kiev occurred last July, when a prominent investigative journalist, Pavel Sheremet, was killed when an explosive device detonated in his vehicle.
