The deaths reportedly occurred on October 24, the second of three days of holidays marking the end of the holy month of Ramadan.
NATO said in a statement issued on October 25 that the International Security Assistance Force (ISAF) had received what it called "credible reports" that several civilians were killed during heavy fighting in Kandahar Province's Panjwayi district.
The statement said ISAF could only confirm that four civilians were wounded while approaching an ISAF patrol and that NATO "deeply regrets any civilian casualty caused."
Afghan central authorities have said they will send a delegation to the region to investigate.
