No mention of how many moved to Russia. By reading what you said, nobody went to Russia even.
I have friends from Donetsk who saw WHICH side the rocket was flying from and it was not Ukrainian territory!
2 June Luhansk airstrike
On 2 June, eight people were killed and more than 20 wounded by a series of explosions hitting the occupied RSA building in Luhansk city.[185] Separatists blamed the incident on a government airstrike, while Ukrainian officials denied this, and claimed that the explosions were caused by a stray surface-to-air missile fired by insurgents.[186] The Organization for Security and Co-operation in Europe (OSCE) published a report on the next day, stating that based on "limited observation", they believed that the explosion was caused by an airstrike, supporting separatist claims.[187]
A CNN investigation found clear evidence that the attack came from the air and the pattern of the craters suggested use of standard equipment on the Su-25, a ground-attack fighter, and the Su-27 – both combat aircraft operated by Ukraine.[185] Analysis of Radio Liberty also concluded that "Despite Denials, All Evidence For Deadly Explosion Points To Kyiv".[188] CNN believed that it was the first time that civilians had been killed in an attack by the Ukrainian air force during the 2014 pro-Russian unrest in Donbas.[185] The next day, Luhansk People's Republic declared a three-day mourning in the city.[189]
