The Taliban denied responsibility, and some villagers told the Associated Press they saw helicopters above the wedding and blamed Western troops for firing into the wedding.
But NATO said none of its troops were involved, and the provincial governor held a press conference where he blamed insurgents and said ball bearings had been found in victims' bodies -- a sign that a suicide bomb had been used.
"On one side they target people who are in favor of the government. Then at the same time, they don't want people to know their real face," Gov. Tooryalai Wesa said, referring to the Taliban's denial.
The attacks have not been limited to Afghans. The first 10 days of June have been one of the deadliest stretches of the war for American troops. At least 19 have died, and McChrystal today acknowledged that the war would get more violent as troops deployed to areas where NATO has not had a significant presence.
"I think it's likely that our casualties and violence will continue to rise particularly through the summer months. They could rise well into the fall." McChrystal told ABC News in Brussels. "We are pressuring the enemy and they are reacting to that. As we predicted, violence would go up the more places we were, the more forces we used to take the momentum away from the enemy."
But a day like yesterday will help reinforce local leaders' doubts about the Americans' ability to protect them. Yesterday afternoon, insurgents dragged a member of the Kandahar provincial council out of his house and killed him, the Associated Press reported.
