The two-month sentence for Malak al-Khatib, who was accused of stone-throwing and possession of a knife, has unleashed a wave of solidarity and support among Palestinians.
"My heart broke when I saw her in court, cuffed and shackled," her mother Khawla al-Khatib told AFP from her home in the town of Beitin near Ramallah.
"I brought in a coat for her to wear because it was cold, but the judge refused to let her have it," the distressed 50-year-old said.
But the case of Malak has brought countless media organisations flocking to her family's door and attracted more public attention than most.

The difference -- she is a girl.
The Palestinian Prisoners' Club estimates that 200 Palestinian minors are held in Israeli prisons, but only four are girls, and Malak is the youngest.
Amani Sarahna, spokeswoman for the Ramallah-based organisation, said it was the first time in years that four female minors were held in Israeli jails, out of the 6,500 Palestinians incarcerated.
A picture of Malak's face framed in black hair, her dark eyes staring squarely into the camera, has been circulating in social media and Palestinian newspapers.
"I don't know why a state like Israel, with the most powerful weapons at its disposal, is pursuing my 14-year-old daughter," Malak's father Ali al-Khatib said.
"They accused her of trying to stab a soldier. Really? A child against an armed and heavily equipped solider, a grown man?" he asked incredulously.
According to the indictment served at a military court, Malak had "picked up a stone" to throw at cars on route 60, which is near the village and serves Israeli settlers as well as Palestinians.
