Boris Johnson pens letter to children of Ukraine

That’s according to Sky News, Ukrinform reports.

The prime minister's letter follows a senior British diplomat warning of credible allegations of sexual violence against children by Russian troops.

"Many of you have seen or experienced things no child should have to witness," the letter states.

He praises the children of Ukraine and asks them to keep in mind that they should be immensely proud "of your country, your parents, your families and your soldiers, and most of all proud of yourselves".

“You are not alone,” the letter adds. “You may be separated from your friends at home, but you have millions of others all over the world.”

'Ukraine is going to win this war'

"Here in the United Kingdom, we fly Ukrainian flags from our homes, offices, churches, shops and playgrounds, even from my own roof in Downing Street, where the windows are filled with sunflowers drawn by British children. Our young people are painting your flag in their classrooms and making blue and yellow bracelets in support of your country.

He stressed his belief in Ukraine’s victory in this war.

"I believe, like your president, that Ukraine is going to win this war. I hope with all my heart that, one day soon, you will be free to return to your homes, your schools, your families. And whatever happens, however long it takes, we in the UK will never forget you, and will always be proud to call you our friends," the letter concludes.

According to UNICEF, two million children have been forced to flee Ukraine, more than half of them arriving in Poland, with another 2.5 million children displaced internally.
