A young Syrian girl who captured international attention with her tweets from war-torn Aleppo has returned to Twitter with a new, frightening message, after a brief disappearance that alarmed many of her followers.

For months, 7-year-old Bana Alabed has turned to Twitter to share harrowing scenes and stories from her war-ravaged hometown of Aleppo, Syria. On Sunday, with the city under fierce attack from Russian warplanes and Syrian government forces, her account disappeared.

The last message posted to Alabed’s Twitter page, which she shared with her mother Fatemah, read, “We are sure the army is capturing us now. We will see each other another day dear world. Bye.- Fatemah #Aleppo."

By Sunday evening, the @alabedbana account had disappeared, with a stock message saying, “Sorry, that page doesn’t exist!”

The account returned to Twitter on Monday, with Alabed's mother tweeting one simple message: "Under attack. Nowhere to go, every minute feels like death. Pray for us. Goodbye."

It's still not clear why the account disappeared, or why it was resurrected. Her last tweet before her absence said she was being captured by the army.

The little girl began tweeting from one of Syria’s fiercest battlegrounds in late September. By early December, she had garnered nearly 200,000 followers.

Bana’s messages conveyed both the horrors of war and the dreams of a little girl. Images posted to the account detailed everything from the simple pleasure of reading to glimpses of rubble-strewn neighbourhoods and bombed-out buildings.

“Tonight we have no house, it's bombed & I got in rubble. I saw deaths and I almost died,” a Nov. 27 tweet read.

“I miss school so much,” another from Oct. 6 said.

Bana even attracted the attention of “Harry Potter” author J.K. Rowling, who sent e-books to the girl after seeing a post in which Bana mentioned her love for the series.

“Good afternoon from #Aleppo,” Bana wrote on Sept. 26. “I’m reading to forget the war.”
