The group of 438 that surrendered seems to be a part of the trapped 72nd Brigade that was surrounded near Isvarino, where there was big fighting a few weeks ago, when Kiev tried to retake the border checkpoints.
There have been rumors of negotiations with the units trapped in the “South Pocket” for several days, and this seems to be the first bunch. There are several tweets saying that another group will surrender today, and that Rostov Hospitals have been placed on alert to receive 50+ UK casualties.
There are several pics and vids of them crossing the border on now on Twitter and youtube.
Per Berezin’s Briefing, the Right Sector militia that was with them, as well as a group of Kolomoisky’s mercs, have not surrendered, and will probably end up fighting to the death.
That makes sense, thanks. Its easy to see the difficulty in attempting to take back a border post and not have to cross borders in the process.
