An aide to a former pro-Russian Ukrainian official was injured in an explosion in Moscow

A car explosion in Moscow, on Friday, injured a former aide to a pro-Russian Ukrainian politician, according to what Russian authorities announced.

A car explosion in southern Moscow injured Sergei Zavorotny, who previously served as an advisor to former pro-Russian Ukrainian Prime Minister Mykola Azarov. Zavorotny was transferred to a hospital in the city to receive medical care, according to the Russian Investigative Committee in Moscow.

Azarov served as Prime Minister of Ukraine from 2010 to 2014, a period during which he fled to Russia in conjunction with the popular protests known as the “Maidan Revolution.”

The Russian Investigative Committee stated that a comprehensive investigation is underway into the explosion that occurred on Kirovogradskaya Street in Moscow.

A video from the scene showed a dark gray SUV that was severely damaged, with its windows apparently shattered.

This incident comes within a series of attacks or assassinations targeting political and military figures inside Russia. On Thursday, a car explosion in St. Petersburg led to the death of a Russian soldier, according to a local investigative committee.

Russia has previously held Ukraine responsible for previous assassinations targeting military officials.

There was no comment from the Ukrainian authorities regarding the explosions that occurred this week.
