The attempted assassination of presidential senior adviser Serhiy Shefir got a swift response from the Ukrainian president.

In a video posted on his official Facebook page, Volodymyr Zelensky, who is currently on a visit to New York  for UN General Assembly meeting, said he learnt about the news at 6 a.m. (EST).

The Ukrainian president promised a ‘strong response’ to the violent act against his ‘close friend and comrade’ Serhiy Shefir.

He argued he doesn’t know who could be behind the attack calling it ‘weakness’ of those who ‘send their regards with firing shots at a car of his friend’.

The Ukrainian president said the incident can’t make him backtrack on his polices and ‘will not affect strength’ of his team.
