Strictly's Karen Hauer reacts as co-star arrested in Ukraine as pro flees Russian invasion

Strictly’s Karen penned a heartfelt message writing: “Stay safe. Travel safely. [Prayer hand emoji].”

Leese commented: “Keep strong. We’re all praying for you.”

Maggie added: “The strength of the fierce Ukrainian people is amazing! Prayers for all.”

Amid the Russian invasion, Ukrainian officials reportedly have mandated men between the ages of 18 and 60 to remain in the country if they are needed for battle, and have restricted them from crossing borders into other countries, Reuters claimed.

Russian forces seized two small cities in southeastern Ukraine and the area around a nuclear power plant, according to the Interfax news agency.
