Motsi Mabuse has confessed there is "nothing" she and Ukrainian husband Evgenij Voznyuk can do to help family members still stranded in the country amid Russia's invasion.
The 40-year-old Strictly Come Dancing judge updated fans and said she is still "in contact" with her in-laws, who have been holed up in bunkers in an attempt to avoid the fighting.
"They spend more than half the day yesterday in the bunkers," she wrote on Saturday, adding: "In Kharkiv there are heavy battles so we can't get to them! At the moment there is nothing we can do."
Mabuse later provided further detail via her Instagram Stories, writing that "every day we sleep not knowing what the news will be the next day".

She added: "I am trying to not make this about me. I am in conflict as to how much I I will open my private life but I know many Ukrainian people and it's personal. It's family."
Mabuse married Voznyuk in 2017 and gave birth to their daughter the following year.
The couple are among the numerous celebrities with links to Ukraine who have spoken out about the horrors caused by Russia's invasion.

Zinchenko later wrote "thank you for your support" on Instagram as he offered his respect to his club for their gesture.
Earlier this week, he had said: "My country belongs to Ukrainians and no one will ever be able to appropriate it."
Resident Evil actor Milla Jovovich wrote on Instagram that she was "heartbroken and dumbstruck" by the fighting in Kyiv — the city where she was born in 1975.
She added: "My blood and my roots come from both Russia and Ukraine. I am torn in two as I watch the horror unfolding, the country being destroyed, families being displaced, their whole life lying in charred fragments around them."
Ashton Kutcher also wrote on Twitter that "I stand with Ukraine", in solidarity with his wife Mila Kunis who was born in the country.
Heroes and Scream 4 actor Hayden Panettiere, who formerly dated Ukrainian boxer Wladimir Klitschko, wrote on Instagram that Putin was an "absolute disgrace".
Klitschko's brother Vitali is the current mayor of Kyiv and both siblings have enlisted to defend their nation.

Panettiere added: "This horrific moment in history sends a terrifying message: the message that in this day and age, in year 2022, it’s okay to violate the rights of free people and allow autocrats like Putin to take whatever they please.
"I’m praying for my family and friends there and everyone who’s fighting."

Elsewhere, Ryan Reynolds and Blake Lively have pledged to match donations of up to $1m (£750,000) to help refugees displaced by the conflict.
Reynolds wrote: "In 48 hours, countless Ukrainians were forced to flee their homes to neighbouring countries. They need protection. USA For UNHCR is providing it."
Ant and Dec referenced the conflict on this weekend's episode of Saturday Night Takeaway with a message before the topical quiz round, declaring there would not be questions about the events.
Ant said: "Obviously the news this week has been dominated by the terrible events in Ukraine so all of our thoughts and prayers are with everyone affected by the situation over there."
