Authorities say two civilians were killed when a suicide bomber attacked a convoy of NATO-led coalition troops in western Afghanistan.

Farah provincial governor spokesman Abdul Rahman Zhawandi said Saturday a man and woman on a motorcycle riding near the convoy were killed when the suicide attacker struck Thursday evening. Five civilians were wounded.

Coalition forces spokesman Capt. Luca Carniel says no NATO forces were hurt in the attack, but did provide medical assistance to the wounded civilians.

Elsewhere, in the central Oruzgan province, police spokesman Fareed Ayal said 20 Taliban fighters and one police officer were killed in an operation late Thursday.

Though the Taliban have indicated they are willing to start peace talks at a new office in Qatar, they have not renounced violence and attacks remain regular.
