"You could hear the shots and the sounds of missiles... many buildings in the city centre were destroyed, like our cinema," the 16-year-old told AFP, recalling the torment in her city after Russia's invasion. But unlike so many others still trapped in Kharkiv, her nightmare ended on March 7 when, after a long journey by train and bus, she arrived in Cusago, near Milan, into the care of the family she has stayed with twice a year since she was nine. Here, her room is filled with cuddly toys and happy memories of Italy that helped sustain her during the worst days.

"If I have to die, I die. But I will have had a happy life, I was lucky, I managed to visit Disneyland in Paris, Berlin and Sicily," she had told her foster parents while in Kharkiv.
Viktoria came to Italy with the help of "The Children of the East," an Italian association which grew out of Europe-wide efforts to give children from Ukraine fresh air and new possibilities after the 1986 nuclear disaster at Chernobyl.
She regularly spent three months in the summer and one month in the winter in the quiet, green surroundings of Cusago.
It was a welcome break from Kharkiv, where she lived in one of Ukraine's notorious children's homes, which host orphans but also those separated from parents deemed unfit for various reasons, from criminality to alcoholism.
Since Russia invaded its neighbour on February 24, Ukraine's second-largest city has faced a daily barrage of Russian rocket attacks, day and night.
When the air raid sirens went off, Viktoria — known as Vika — took refuge in a school basement. Wrapped in a sleeping bag, she passed the time by playing Burraco, an Italian card game.
With her host mother, 47-year-old graphic designer Michela Slomp, nearby she says her future is Italy.
"My house is here, I want to finish school and go to university," she said in almost perfect Italian, her face lit up with a large smile.

Vika was not even born when Chernobyl's number four reactor exploded on April 26, 1986, causing the world's worst nuclear accident, killing hundreds and spreading radioactive contamination west across Europe.
But the desire to help the children of Ukraine lives on through the "Children of the East" association, run by Federica Bezziccheri.
Since the war began, her telephone has rung day and night with Italian families searching desperately for their foster children — and young Ukrainians trying to get out. "We are experiencing the war live. When we call the children via videolink, we can hear the bombing," Bezziccheri said.
'Die like rats'
"The girls tell us how they only had to walk a hundred metres to see the dead. The boys signed up as volunteers, filling sandbags or digging trenches," she told AFP at her apartment in Milan.
"Some young people say it is better to risk being injured or killed helping their country, than to die like rats in a cage under a building."
So far, the association has brought 280 refugees to Italy, out of more than 100,000 Ukrainians who have sought refuge in the Mediterranean country.
The Italian foster family of Yana Alieva, 20, got her out of Kharkiv in January, anticipating Russia's invasion.
She too was brought up in a children's home but is now safe in a Milan apartment, a blue and yellow Ukrainian flag draped from the balcony.
"I am heartbroken. In a few days my world has disappeared. My boyfriend and my friends survived the bombs in the cellars before moving to safer areas, I fear for those who stayed," she said.
She is also angry. Before the war, "we were all united, Russians and Ukrainians, as one people", but now "we see who they really are."
She has enrolled in the Catholic university in Milan, but hopes to return to Ukraine after the war.
"My home is there," she said, adding she hoped "to participate in the reconstruction of my city and make it even more beautiful."
On average, every day over the last 20 days in Ukraine, more than 70,000 children have become refugees," James Elder, spokesman for the UN children's agency UNICEF, told reporters in Geneva.
President Zelensky said conditions in Mariupol, which has seen the worst fighting of the nearly eight-week long war, continued to worsen, though Reuters witnesses said a few dozen civilians managed to leave the city on Wednesday in a small bus convoy.
"My family and I are horrified seeing pictures from Ukraine and heartbroken for the innocent people who have been so terribly affected. We stand for peace," Federer said on Twitter.
Jill Biden called the show of solidarity "amazing" but also "just the beginning.” She said it was inspiring for Romanians "to welcome all these refugees into their homes and offer them food and clothing and shelter and give them their hearts.
The asteroid, named 2023 DZ2, is estimated to be 40 to 70 metres (130 to 230 feet) wide, roughly the size of the Parthenon, and big enough to wipe out a large city if it hit our planet.
The two installations are part of the latest exhibition by 72-year-old American photographic artist Roger Ballen, which opens in Johannesburg, South Africa, next Tuesday.
A tweet from a US server went viral this week after she criticised a group of European tourists for not leaving an adequate tip after spending US$700 (£570.25) on food.
