  On 24 February 2022, Russia invaded Ukraine, also known now as
Russo-Ukrainian War. We have initiated an ongoing dataset acquisition from
Twitter API. Until the day this paper was written the dataset has reached the
amount of 57.3 million tweets, originating from 7.7 million users. We apply an
initial volume and sentiment analysis, while the dataset can be used to further
exploratory investigation towards topic analysis, hate speech, propaganda
recognition, or even show potential malicious entities like botnets.
