Up to seven civilians were killed Friday after a vehicle ran over a roadside bomb in eastern Afghanistan's province of Logar, an official source said.
"A station wagon set off an Improvised Explosive Device (IED) along a main road in Baraki Barak district at around midday, leaving seven people aboard the car killed," the provincial government spokesman Din Mohammad Darwish told Xinhua.
The victims were members of one family, Darwish said, adding " four children and a woman were among the killed."
The official blamed the Taliban insurgent group for the attack.
The Taliban has largely been using home-made IEDs to launch suicide attacks and roadside bombings against security forces but the lethal weapons also inflict casualties on civilians.
Nearly 3,700 civilians were killed and more than 6,800 others wounded in conflicts and Taliban-led attacks in 2014, according to official figures released by UN mission in the country.
