NATO says a baby was killed during a night raid targeting militants in central Afghanistan.

A statement says a gunbattle broke out Saturday night after a joint international-Afghan force came under fire from several locations as it approached a compound in Uruzgan province.

It says four suspected insurgents also were killed.

Sunday's statement says "one woman with minor wounds and a baby who suffered fatal injuries were found" after the fighting ended.

It says the civilian casualties occurred despite efforts to protect women and children at the compound.

U.S. Army Col. Wayne Shanks, a NATO spokesman, has expressed regret for "this tragic loss of innocent life."
