Authorities in eastern Afghanistan say a suicide bomber has killed the head of a provincial peace council and his son.

The peace envoy was on his way home from Friday prayers in Kunar province at the time of the attack. Another person was wounded in the assault.

The peace council works to bring Taliban fighters to the negotiating table to discuss laying down their weapons.

The negotiating body came under attack last year when a suicide bomber assassinated its chief, Burhanuddin Rabbani. That suicide attack was Afghanistan's most notorious assassination since the U.S.-led invasion ousted the Taliban.

In southern Afghanistan, officials say a NATO fuel tanker crashed Friday, killing seven people and injuring three others.

The tanker flipped over and burned in the Panjwayi district. A passing minivan was engulfed in the flames.

Elsewhere in southern Afghanistan, NATO says a bomb blast killed one soldier from coalition forces. The victim was not identified.
