In Dand locality of neighboring Nawa district, four militants lost their lives in a sortie launched by the air force, according to the statement.
In addition, the Afghan air force also destroyed one Taliban's attack tunnel in Miwand district of southern Kandahar province, the statement noted.
Taliban militants, who ruled the country before being ousted in late 2001, renewed armed insurgency, killing government troops as well as civilians.
They frequently attack district offices, military camps, installations and security checkpoints, while the Afghan military respond with airstrikes on militant targets in the countryside.
