The AP reports that Five killed at Afghan wedding party after revellers fire rocket-propelled grenade:

KABUL (AP) - Five people were killed and six wounded when guests at an Afghan wedding party fired a rocket propelled grenade into the air, only to have it land nearby, an official said Wednesday.

"One of the grenades landed back on the ground near the wedding party, but it hadn't gone off," said Abdul Matin Hasankhiel, a senior military commander in the area.

"A commander attending the wedding went to see why it didn't explode. When he touched it, it went off."

Hasankhiel said revellers fired assault rifles and seven rocket-propelled grenades to celebrate the wedding. Guns are often fired into the air to celebrate marriages in Afghanistan, but that tradition does not often include firing heavier munitions, such as grenades or rockets.

Good thing they don't have artillery.
