KABUL: An ambulance struck a roadside bomb, killing a pregnant woman who was being rushed to the hospital and four of her family members, the Afghan Interior Ministry said.

The statement said the ambulance was driving on a road Monday in the northern province of Sar-e-Pul when it hit the buried explosive. It said the dead included two women and two children.

Meanwhile, an official said another four civilians were killed in an attack in the east.

Ghazni provincial spokesman Fazel Ahmad Sabawon said two women and two children died when a mortar fired by insurgents hit their home. He said the militants appeared to be aiming for a government building nearby, but missed their target. He said the incident happened in Ghazni province's Gilan district.
