Can this sweet little girl get out of Aleppo alive?

Every morning, after the children go to school, I turn on my computer to check that Bana Alabed is alive and unharmed. I do the same at night. I have never met Bana. She is a sweet-faced, skinny seven-year-old girl who tweets from rebel-held east Aleppo with the help of her mother, Fatemah, an English teacher.
