Kateryna's parents woke her at 5 a.m., told her to pack her documents and phone and flee from their home in Dnipro in eastern Ukraine to relatives in Poland.
It took the 19 year-old three days to reach the Medyka border crossing in Poland, some 1,000 km (620 miles) from Dnipro. It was the first time she had travelled alone, without family or friends.
But waiting to board a train to stay with an aunt living in the western Polish city of Wroclaw just hours after she arrived in the country, Kateryna, who did not give her last name, said she now felt safe.
