A grieving Ukrainian man has taken his son's place in the armed forces after he died fighting the Russians.
The man, who has not been identified, was filmed on the border with Poland returning to Ukraine.
Looking emotionally drained, he tells ViceWorldNews reporter Valerie Kipnis that his 23-year-old boy was killed fighting in Kharkiv.
"You see I am overwhelmed by feelings," the man explains.
"My son told me 'dad, it's bad, it is very bad. But we are holding on, it's okay."

Someone off camera explains that the man "wants to take his place", referring to the gap in the Ukrainian forces left by his son's death.
The grieving dad turns his attention towards the Russian soldiers and their families and implores them: "Don't come here. You will die. You killed my son. I will kill your son."
The man's son is one of at least 1,300 Ukrainian fighters who have lost their lives in battle, according to President Volodymyr Zelensky's latest update given on Sunday.
Kharkiv, in the north east of the country, is Ukraine's second city and one of the areas worst impacted by Russian attacks.

The cities of Kharkiv, Chernihiv, Sumy and Mariupol are all surrounded by Russian forces, and subject to some of the most brutal shelling and missile strikes.
BBC correspondent Quentin Sommerville walked among a dozen corpses at a petrol station forecourt on the frontline near Kharkiv.
Ukrainian troops said they were 'fighting like lions' as showed Mr Sommerville some of the dead soldiers lying dead in the snow.
One Ukrainian soldier said: "The Russians are fighting like soldiers of 1941.
"They are attacking just like in front, they don't do any manoeuvres. They have a lot of people, tanks and vehicles but we are fighting for our land and we are protecting our families.
"It doesn't matter how they fight, we fight like lions and they won't win."
On Monday the mayor Kharkiv said the city had been under constant attack by Russian forces, who had fired at central districts causing an unspecified number of casualties.
"They're firing at us constantly," Mayor Ihor Terekhov said on national television.
