A civilian car hit a freshly planted land mine in southern Afghanistan on Thursday, killing six people and wounding six others, while Taliban militants beheaded an old woman and her grandson accused of spying, officials said.

Afghan officials refer to the Taliban and other militants as “the enemy.” Militants usually attack foreign and Afghan troops with mines and other roadside bombs, but most of the victims in such attacks have been civilians.

In Uruzgan’s Dihrawud district, Taliban militants beheaded a 60-year old woman and her grandson on Wednesday, said provincial police chief, Juma Gul Himat. The militants accused the woman of spying for government and NATO forces.
