It had been a normal day for 18-year-old twins Makarem and Ikram when their school came under fire.
Makarem was in an English literature class and Ikram was in a science lesson when they heard "strange sounds" coming from outside the school in Sudan.
Then the shelling started.
Makarem says her shoulder "tilted" as she was struck. Screaming, her classmates dropped to the floor to avoid shellfire and find somewhere to hide.
"We took cover beside the wall and the girl who was standing in front of me put her hand on my shoulder and said: 'Your shoulder is bleeding.'"
