Ukrainian teachers created an online teaching platform to try to “save the minds of Ukrainian children”.

“Once we launched it, I wrote a neutral letter, offering the classes to all of the parents,” explains one teacher. “I didn’t know who was pro-Ukrainian or pro-Russian, and they knew my home address and my relatives”.

Ukrainians say even uttering the word “occupation” can result in Russian authorities visiting your home. If there is any evidence of loyalty to Ukraine, such as a child’s homework being written in Ukrainian instead of Russian, a trip to the police station could follow.

In the classrooms, Portraits of Vladimir Putin now hang on the walls. The pupils must both learn, and sing, the Russian national anthem. They are even obliged to write “inspirational letters” to Russian soldiers.

This is how Ukrainian children are educated in territories occupied by Russia. They are taught that Ukraine isn’t a real country - and Nataliia says, if a child challenges the curriculum, their parents are threatened with beatings or torture.
