A video uploaded to YouTube today shows a BMP-2 IFV on the streets of Antratsit, in the south of the Lugansk oblast. The vehicle is definitely not flying a Ukrainian flag, but neither does it appear to be either the Russian or the black, blue and red of the self-declared Donetsk People's Republic (now to be merged with their counterpart in Lugansk into the self-proclaimed state of Novorossiya). The flag here is made up of three horizontal stripes of blue, white and red. It appears to in fact be the 1992-2003 Yugoslavian flag. Could this suggest volunteers from the Balkans?

At least two Ukrainian BMP-2s were destroyed in combat near Rubezhnoye to the north of the region on Thursday. It is possible one vehicle was captured here. Meanwhile the BBC's Olga Ivshina reported seeing a BMP carrying separatists out of Karlovka following the devastating ambush on Ukrainian Donbass Battalion volunteers there.
