There is no general understanding of correlation between verbal and nonverbal components in communication process at the current stage of both domestic and foreign linguistics development. However, most of the researchers believe that nonverbal organization of an individual’s speech plays a significant role in presenting the informative content of an utterance. One of the key elements of nonverbal communication is kinesics, elements of which form a visual semiotic system. In this regard, the aim of this study is to examine kinesic components of terrorist nonverbal behavior – on the material of 8 Islamic State militants’ video messages, selected by continuous sampling, we attempt to analyze the peculiarities of facial gesture, gesticulation, pantomimicry and eye contact established by the speaker. The results of the research show that despite the informative value of kinesic components of an individual’s nonverbal behavior, only the complex of nonverbal and verbal means, decoded simultaneously, is efficient enough to effectuate the speaker’s pragmatic intention.
