KYIV — Ukraine's military intelligence chief, Kyrylo Budanov, has warned that Russia is trying to apply what he called the "Korean scenario" to Ukraine, having failed to take the capital and depose the legitimate government.
He said Russian President Vladimir Putin would try to impose a demarcation line separating the eastern and southern regions from the rest of Ukraine, since he would not be able to absorb the whole country.
Gen Budanov predicted this quasi-state would be unviable, given the resistance of the local population. He said that what he described as a "total Ukrainian guerrilla safari" was about to open.
The general's warning came amid continued reaction to US President Joe Biden's speech in Poland on Saturday, in which he said that Putin should not be allowed to remain in power.
Biden's Secretary of State, Antony Blinken, denied that the US had any plans to bring about regime change in Russia or anywhere else.
And French President Emmanuel Macron warned against the verbal escalation of the war in Ukraine, saying this would make it impossible to bring about a ceasefire and the withdrawal of Russian troops.
But this isn't the first time President Biden has veered off-script and thrown a live grenade into an otherwise well-prepared, measured speech.
Ukraine accuses Russia of forcibly deporting its people from war-ravaged cities to Russian-held territory, or all the way to Russia proper. Satellite images show a temporary camp east of Mariupol that is housing an estimated 5,000 people.
Forcibly deporting civilians is seen as an international human rights abuse - but Russia denies it is doing anything of the sort.
Ukraine has described plans by the self-proclaimed Luhansk People's Republic to hold a referendum on joining Russia as having no legal basis.
Ukraine's foreign ministry spokesman said any referendum would be fake and warned that Moscow would face further isolation if it went ahead.
Earlier, the leader of Luhansk said a vote could happen soon and that the population would vote overwhelmingly to leave Ukraine and join Russia. He later rowed back on that statement, Tass reports, to clarify that he had only been stating a personal opinion - and that no preparations were actually being made for such a vote.
Last month, Russia formally recognized the Luhansk and Donetsk breakaway republics as independent states, paving the way for Russian troops' invasion of Ukraine.
The road to war for CJ, Elliott and Kieran ran through Facebook, a cheap flight to Poland and a cold night sleeping outside a railway station.
The BBC's Jonah Fisher met the former British soldiers in Ukraine just outside a school, a couple of kilometres from the border with Poland. They were waiting for a minibus to transport them, along with other recruits, to Lviv.
"I just can't sit at home and watch what's going on and carry on as usual," said CJ Darton, who served for seven years with the Royal Anglican Regiment.
When Russia invaded Ukraine in February, he almost immediately began making plans to volunteer.
Trafficking rings are notoriously active in and around Ukraine - and the fog of war is perfect cover.
Elena Moskvitina is one of many Ukrainian refugees who have fled the fighting, only to find themselves menaced by pimps, traffickers and abusers.
Elena, who is now safe in Denmark, told the BBC's Katya Adler how she escaped the clutches of fake volunteers at a refugee center who offered to give her and her children a lift to Switzerland, along with a group of other women.
To get the men away from her family, Elena promised to meet them when the other women were in their van. But as soon as they left, she grabbed her children and ran. — BBC
