In this latest incident, NATO forces shot dead two Afghan boys, ISAF admitted on Saturday.

The shooting took place on Feb. 28 in the Shahid-e Hasas District of Afghanistan's Uruzgan Province.

Agence France-Presse reports that the children were 7 and 8 years old and were tending cattle when Australian soldiers fired at them in a "'mistaken' retaliatory attack."

There have been a string of incidents in which Afghan civilians, including children, have been killed by NATO forces. Just three weeks ago, five children were among 10 civilians killed by a NATO missile attack.
