At least nine students have been killed in an explosion in southeastern Afghanistan, according to the Pajhwok news agency.
The exhibition took place in the Takhar region on Saturday morning.
The bomber struck shortly after noon in front of a school.
So far, no further details have been released.
In October, two blasts hit a mosque in the Jo Dara area of Huska Meina province during Friday prayers. At least 62 people were killed.
Afghanistan has long been hit by instability. The government has been fighting the Taliban for almost two decades, as well as the terrorist organization ISIS, which has been active in the country since 2015.
