Authorities in volatile northwest Pakistan say six members of a family were killed when a grenade exploded in their vehicle Sunday.
Officials in the North Waziristan tribal region say a husband, a wife and their four children were killed instantly by the blast. Four other people were wounded.
Officials say they do not know whether the family was transporting the grenade or if it was planted in their vehicle.
On Saturday, 12 children in northwest Pakistan were killed when they mistook a bomb for a toy and began playing with it.
A local police official, Said Zaman, said the children found the football-shaped bomb near their school in northwest Pakistan's Lower Dir district. It is not clear whether the bomb was placed there accidentally or deliberately.
Some information for this report was provided by AFP, AP and Reuters.
