A 7-year-old boy accused of being a spy was hanged by Taliban militants, according to published reports Thursday.

The child was allegedly put on trial by the militant group and later found guilty of working for Afghanistan President Hamid Karzai’s government, reports the Daily Mail.

Karzai called the act a “crime against humanity.”

“I don’t think there’s a crime bigger than that that even the most inhuman forces on earth can commit,” Karzai said.

The child was publicly hanged in the Taliban stronghold of Helmand province, a local official told The Associated Press.

“A 7-year-old boy cannot be a spy,” Karzai added. “A 7-year-old boy cannot be anything but a seven-year-old boy, and therefore hanging or shooting to kill a seven-year-old boy… is a crime against humanity.”
