Russia said Saturday it was withdrawing from the eastern Ukrainian city of Lyman, a day after Russian President Vladimir Putin ordered the city to be annexed.
The Russian Ministry of Defense posted on Telegram that it was withdrawing from the city because of the threat of encirclement.
An hour before the announcement, the Military of Defense posted a video of its soldiers flying the Ukrainian flag.
The city of Lyman, which has a pre-war population of 20,000, was encircled by Ukrainian troops this week as they attempted to take control of the city.
Putin boasted about the historic and permanent nature of the annexations in a Friday speech.
In May, Russia took control of Lyman, giving it an important rail and supply hub. Putin signed a decree Friday annexing the territories after the referendums passed in the Ukrainian provinces. The move was denounced by the UN Secretary-General as a dangerous escalation.
A senior Ukrainian military official told the New York Times that the Russians have nowhere to go.
The Ukrainian army is trying with all its might to blacken this, said the leader of the self-proclaimed Donetsk People's Republic.
Forbes' David Axe writes about the 752nd Guards Motorized Rifles, which has a tragic tradition of getting cut off, surrounded and all but destroyed. During the First Chechen War in 1994, the same group was forced to withdraw.
Putin claims that four Ukrainian regions are part of Russia.
25 people were killed in one of the annexed Ukrainian provinces.
There is a tragic history of defeat for a Russian military unit.
