A Syrian woman who gained fame through a Twitter account in her daughter's name that shows the brutal horrors of life in Aleppo, posted a sad farewell on Sunday.

"Under heavy bombardments now, can't be alive anymore," she posted. "When we die, keep talking for 200,000 still inside. Bye."

The woman, and her 7-year-old daughter, Bana, whom the account is named after, gained viral fame just a few months ago sharing gritty and heartbreaking posts of what life is like for children trapped inside the bombardment of Aleppo.

But she told NBC News that Sunday's bombardment was "the hardest day." NBC News has previously only referred to her as Fatemah, out of concern for her safety.

"(Bana) wants to live and peace returned," she aid in a direct message. "She wants real help for the murder stopped."

Hours after her goodbye tweet on Sunday, Fatemah said her home had been destroyed during a night of bombings. She shared a photo of a dust-covered Bana, usually smiling and joyful, looking bemused and shell-shocked.

"Tonight we have no house, it's bombed & I got in rubble," read the tweet, which was "signed" by Bana. "I saw deaths and I almost died."

UPDATE: The family tweeted early Monday morning, saying: "Under heavy bombardments now. In between death and life now, please keep praying for us. #Aleppo"

Followed by another tweet hours later: Message - we are on the run as many people killed right now in heavy bombardments. We are fighting for our lives. still with you.- Fatemah
