Could it be we dropped a bomb on the wrong people?

Again?:

At least 12 Afghan road construction workers have been killed in an air strike by the US-led forces in Afghanistan, a provincial governor has said.

Another local official said that up to 25 men were killed in the attack late on Tuesday in the province of Nuristan, northeast of Kabul.

"We had reports that rebels were there," Tamimi Nuristani, the governor of Nuristan, told the AFP news agency.

"There was an air strike by coalition forces but later we found out that 12 people, all local road workers, were killed. The road workers were in a tent which was hit by one bomb. All died," he said.

The media office of the US-led coalition forces said it was trying to find out what happened.

"Something happened but we are not sure exactly what," Chris Belcher, a spokesman, said.

Well, Mr. Belcher... we dropped a bomb. On 12 innocent people. Who died. Oooops.
