Russian forces pushing their grinding offensive in eastern Ukraine "appear to be" resorting to World War I-era chemical weapons in their bid to dislodge Kyiv's defending units, according to the latest battlefield update from the Institute for the Study of War.

Colonel Oleksandr Shtupun, the spokesperson for the Tavria Ukrainian military group operating on the southeastern front line, said on Tuesday that Russian forces had been using "K-51 grenades with chloropicrin" in their attacks on Kyiv's positions.

3-RUSSIAN DIPLOMAT URGES US TO REVEAL INFORMATION ABOUT ACTIVITIES OF LABS IN UKRAINE

Abstract: Previous research dedicated a lot of effort to investigation of the activities of the Internet Research Agency, a Russia-based troll factory, as well as other information operations. However, those studies are mostly focused on the 2016 U.S. presidential election, Brexit, and other major international political events. In this study, we have attempted to analyze how narratives about a domestic issue in Russia are used by malicious actors to promote harmful discourses globally and persuade an international audience on Twitter.
