Video has emerged purportedly showing Ukrainian troops mocking Vladimir Putin's generals after capturing a command post in the Russian border region of Kursk.
In the clip, which was shared by blogger for WarTranslated Dmitri Masinski, two soldiers jokingly say: "We asked for two tanks!"
Laughter erupts among the men, as another solider says: "Grab a pen and write that down."
While holding a phone, one soldier shouts the last names of former Russian defence minister Sergei Shoigu and current army chief Valery Gerasimov, before bellowing: "Where is the ammo?"
Earlier today, senior Kyiv officials said Ukraine was creating a "buffer zone" in the region and planned to organise humanitarian assistance and evacuation corridors for civilians looking to go either to Russia or to Ukraine were under way.
