Israel has said a Palestinian teenager who was among the youngest prisoners and detainees it freed under a Gaza truce cannot return to his former school in Jerusalem until at least mid-January after a period of probation, Reuters reports.

Ahmad Salaymeh’s family sees the ban as a violation of his rights as well as a reminder of Israeli control over Palestinians in Jerusalem. The boy denies any wrongdoing.

After a week’s recuperation at home, he wanted to resume his studies. But then the school informed Salaymeh’s father that his return was being prevented by Israeli authorities.

“I am sad because I can’t see my friends and I am missing classes, so I have to study again, and I may need to repeat the school year,” Salaymeh told Reuters. “I lost this year.”

Israel’s Education Ministry said Salaymeh would be kept from school at least through Jan 10, the end of the winter vacation, which begins on Dec 23.

“Pupils who are released prisoners will not learn within the educational system and will be regularly accompanied by a probationary officer,” the ministry said in a statement.
