KABUL (AP/BBC) --- At least 27 people have been killed in a missile strike by the U.S.-led occupation forces in Afghan's eastern Nangarhar province.

Local people say that the group was a wedding party and most of the dead were women and children.
Meanwhile Afghan President Hamid Karzai has ordered an investigation into a missile attack by U.S. helicopters on Friday.
The chief government official in the Deh Bala district of Nangarhar province said villagers reported that between 30 and 35 people walking in a group toward a wedding were killed in a United States bombing. Up to 10 others were wounded, he said.
Deh Bala district governor Hamisha Gul told AFP news agency that 22 people had been killed in the strike -- 19 of them women and children.
He said the information had come from police and other officials investigating the incident in the remote area.
Haji Amishah Gul said the group was hit while resting in the shadow of a mountain. Those killed included men, women and children, he said.
No other officials could immediately confirm Gul's claim because of the remote location of the incident.
President Hamid Karzai ordered the defense and interior ministries, as well as local government officials, to investigate attack in eastern Afghanistan.
Karzai's statement quoted allegations from Gov. Tamin Nuristani, the governor of Nuristan province, as saying that 15 civilians were killed and seven wounded.
However, the Ministry of Defense on Sunday said up to 20 fighters were killed and wounded in an air attack in Kunar province Friday. The area of the attack is on the border between Kunar and Nuristan, and both statements referred to the same incident.
The U.S.-led coalition insists those killed were fighters who had previously attacked a NATO base with mortars.
Karzai's statement appeared to indicate that Afghan civilians were fleeing in cars during the time of Friday's airstrike by coalition helicopters because of a warning from the U.S. coalition.
“Coalition forces are saying that this operation was against armed insurgents in the area, but Gov. Nuristani is insisting that three hours before this airstrike the people were informed by international forces that they should leave the area because of a possible airstrike against insurgents,” the statement said.
Perry said Sunday that military reports still indicated that Friday's strike in Nuristan hit two vehicles carrying fighters who had attacked a NATO base with mortars.
U.S. coalition reporting indicated that the Kunar and Nuristan incidents, reported by the Ministry of Defense and Nuristani respectively, were the same, he said.
