A blast by the roadside in north-eastern Afghanistan killed nine children as they made their way to school.
Eight boys and a girl aged between seven and 10 accidentally stepped on a deliberately-planted mine. So far, no one has claimed responsibility for the bomb.
The landmine blast took off at 8:30 am.
The spokesperson for the Takhar provincial governor alleged that the roadside device had been planted by the Taliban, which had taken control of Takhar Province for several weeks before Afghan forces recently regained control.
The Taliban has not responded to a request for comment on the incident.
Last May, a landmine killed seven children and wounded two more in the southern province of Ghazni.
In February, seven children were killed and 10 more wounded in Laghman province when a mortar shell exploded as they played with it.
Just last month, a UN report said 1,174 Afghan civilians had been killed over the three months until the end of September. More than 3,000 people have also been injured during this period, the UN report added.
