At least three people were killed in the region on Monday, Donetsk’s governor said on Tuesday. Many of those killed and captured in eastern Ukraine appear to be civilians mobilized and sent into battle with little or no military training. At least 21 mobilized men from Moscow surrendered earlier this week outside the city of Svatove, according to an adviser to Ukraine’s interior minister, who released a video of the captives saying they were “thrown to slaughter” without any training or food before commanders “they fled.” Separately, Russia has also been seen installing “dragon’s teeth” defenses deep behind the front lines amid apparent fears of a shock Ukrainian advance. The UK Ministry of Defense said in its daily briefing on Tuesday that the concrete pyramid anti-tank structures, known as “dragon’s teeth”, have been installed around the city of Mariupol, which is vital to Russia as a “land bridge” between of mainland Russia. and the Crimea. Dragon’s Teeth have also been sent to prepare fortifications in the occupied regions of Zaporizhzhia and Kherson, the defense ministry said, adding that the use of anti-tank defenses could be part of efforts to “prevent any rapid Ukrainian advance in the event of breakthroughs”. .
