A video of a young girl singing Let it Go from Disney's Frozen has won the internet since it first surfaced on Thursday.

The video of the girl, named Amelia,was posted by Marta Smekhova on Facebook, and shows her singing the song in a bomb shelter in an undisclosed location in Kyiv.

'From the first word in the [bomb shelter] came complete silence... everyone put their business aside and listen[ed] to a song by this girl who was just beaming light... even men couldn't hold back the tears,' Smekhova wrote.

She goes on to write about her visit to the shelter.

'Seeing in one of the Kyiv bomb storage, how children draw bright pictures in half-darkness, I, of course, couldn't silently pass by... stopped, praised, offered to do a little exhibition to somehow decorate this not so happy place,' she wrote.

However, she wrote that when she spoke to Amelia, she found her to be talkative.

'Amelia told me that besides drawing, she loves to sing... and whispered shared her dream that she wants to sing on a big stage in front of the audience...

That's when Smekhova asked her to sing as she had an audience.

Amelia sings the Oscar-winning song in Ukrainian language and one can see people filming her and some are lying on the floor as she sings.

The Facebook video has been shared hundreds of times and received a lot of media attention, too including from Idina Menzel who sang the song for the 2014 movie.

Menzel tweeted the video saying "we see you."

Social media users have shared the video saying the girl represents courage in times of adversity.
