A roadside bomb killed seven members of an Afghan family including three children in the restive south, officials said on Tuesday, the latest civilian casualties ahead of the Taliban's traditional spring fighting season.
The explosion occurred on Monday as the family was heading home in a minivan after a shopping trip in Ghazni province, a provincial spokesman said.
"The minivan hit a landmine planted by the Taliban, killing seven members of a family, including three children, three women and one man," Shafiqullah Nang told AFP.
Qasem Disiwal, district chief of Andar, where the explosion occurred, confirmed the incident, saying the area was heavily mined by the Taliban after they retreated following an Afghan army operation.
"Taliban have planted thousands of mines in Andar. Afghan forces defuse 20-30 landmines every day," Disiwal said.
No group has so far claimed responsibility for the blast, but roadside bombs have been a weapon of choice for the Taliban in their their battle against the US-backed government and foreign forces.
The bombs often target Afghan security forces, but they have also taken a heavy toll on civilians.
The number of civilians killed and wounded in Afghanistan jumped 22% in 2014, a recent UN report said, as NATO troops withdrew from combat.
The United Nations Assistance Mission in Afghanistan attributed the rise to an intensification in ground fighting, resulting in a total of 10,548 civilian casualties last year.
President Barack Obama last week reversed plans to withdraw around 5,000 US troops from Afghanistan this year, an overture to the country's new reform-minded leader, President Ashraf Ghani.
The Taliban, waging a deadly insurgency since they were ousted from power in late 2001, warned that the announcement would damage any prospects of peace talks as they vowed to continue fighting.
Afghan forces are bracing for what is expected to be a bloody summer push by the Taliban.
