Afghan officials say six civilians have been killed in twin explosions in eastern Afghanistan.

Monday's attacks took place in the Dangam district of Kunar province.

Authorities say a civilian vehicle struck a roadside bomb and when passers-by ran to assist the driver, another mine exploded. Six people were killed and two wounded in the blasts.

Also Monday, officials in the Czech Republic said a soldier wounded in Afghanistan in July has died.

The soldier was shot while on a mission in Wardak province in central Afghanistan. He was flown home to a Czech hospital almost immediately but died from his injuries Sunday.

More than 7,000 Czech soldiers have served in Afghanistan in the past decade. Five have been killed.

Also Monday, NATO said one of its service members was killed in southern Afghanistan. The coalition said it was investigating the circumstances of the soldier's death and gave no other details.
