Russia has turned a key Ukrainian road link into a highway from hell with chicken hunt drone strikes on civilians, in what officials say is yet another example of Vladimir Putin's war crimes.

The M-14 Kherson-Mykolaiv highway has become a death alley, according to a senior official, who has told residents to avoid it.

A hostile drone strike by Vladimir Putin's forces attacked a prosecutor's vehicle and wounded two people.

'We have been observing high activity of Russian drones along the M-14 Kherson-Mykolaiv highway,' said Oleksandr Prokudin, head of the Kherson Regional Military Administration.

'The enemy is purposefully attacking civilian transport. Therefore, I strongly urge you: do not travel along this route unless absolutely necessary.'
