The shrill bell sends hundreds of students rushing towards their classrooms in a town near Damascus, which only months ago was the scene of fierce fighting between rebels and regime forces.
Their hometown of Kafr Batna, in Syria’s Eastern Ghouta, was recaptured by the government just this spring after a blistering offensive against opposition factions that held the area for nearly five years.
More than four million Syrian students are heading back to school this month in areas under government control across the country, the education ministry says.
In a modest classroom, Batoul Jardat chats with high school students enrolled in her Arabic language course.
The instructor, 30, is herself a Kafr Batna native, but she fled five years ago for the relative safety of Damascus. She returned earlier this year, after the army announced that Ghouta and Damascus as a whole were finally “safe”.
Like her students, Jardat says she is still getting used to a new routine.
“I feel strange, just like them,” says the young woman, dressed in a white headscarf, long overcoat and stripey blue-and-white T-shirt.
