Those wounded by the blast on the main highway included two children from the same family as the dead boy, said Ghulma Hazrat, a police officer at the scene.
“One ISAF soldier suffered minor injuries,” Isaf said in a statement.
The main road, known as Highway One, is the main link between western Afghanistan and Kandahar.
The highway has seen several attacks in the past months, including suicide bombings by Taliban fighters opposed to the Isaf presence and the Afghan government.
Taliban fighters have been blamed for most of nearly 140 suicide bombings last year, which killed hundreds of people, mainly civilians.
