This study uses John Rogers Searle's (1969) theory of speech acts and focuses on the types and functions of illocutionary speech acts. In the research results, 15 comments were found containing illocutionary speech acts with different functions which were dominated by expressive illocutionary speech acts. There are 3 assertive illocutionary speech acts, 1 directive illocutionary speech act, 10 expressive illocutionary speech acts, and 1 commissive speech act. The comments reflected criticism of the invasion and disapproval of Russia's actions, as well as expressions of disappointment, hatred and concern about the escalation of the conflict and its impact on civilian casualties.
