A 7-year-old Syrian refugee whose Twitter posts from the besieged city of Aleppo put a face to the country’s civil war for thousands of followers and turned the girl into an international celebrity, has been offered a book deal.

“The world must end all the wars now in every part of the world,” Bana al-Abed wrote this week on Twitter.

“I am so happy to have this opportunity to tell my story and the story of what has happened in Aleppo to the world,” Bana added in a statement released by the publisher Simon & Schuster. “I hope my book will make the world do something for the children and people of Syria and bring peace to children all over the world who are living in war.”

The book, “Dear World,” will be published this fall. A company spokesman would not disclose financial details.

Bana’s Twitter account — created and operated by her mother, Fatemah — has more than 370,000 followers. The account, created in September 2016, highlighted the conditions in the rebel-held part of Aleppo during a government push to recapture what was then Syria’s largest city.
