Wasil Ahmad was shot in the head twice by Taliban militants riding a motorcycle as he made his way to school in the volatile city of Trin Kot, capital of southern Uruzgan province, months after leaving a militia force and enrolling in the fourth grade.
The cherubic pre-teen had become a poster-child for pro- government forces after he reportedly helped his uncle and other militia fighters break a Taliban siege last summer in his home province.
The Taliban, who have been waging an insurgency against the government since being driven out of power by US-led NATO forces in 2001, claimed responsibility for the killing.
"It's such an appalling, tragic case," Patricia Gossman, senior Afghanistan researcher at Human Rights Watch, told AFP.
"There were two crimes in this case: that he was killed, and that a child his age was fighting at all," she added.
"One side made him a hero and the other side killed him. Both sides ignored the law and acted illegally," added Rafiullah Baidar, spokesman for the Afghan Independent Human Rights Commission added.
Wasil's uncle, Mullah Abdul Samad insisted however that Ahmad had taken up arms voluntary to avenge his father's death. "Nobody encouraged him, he wanted revenge," he said.
