Officials in Afghanistan say five civilians, including a woman and a child, have been killed in the bombing of a minibus in the central province of Wardak.
Provincial government spokesman Sahidullah Shahid told journalists four passengers survived the June 11 attack, which is suspected of having been carried out by Taliban militants.
The blast came one day after another roadside bomb killed five people in northern Afghanistan, and a week after twin suicide bombings killed more than 20 people in Afghanistan's south.
Taliban militants regularly use improvised roadside bombs to target Afghan and Western military forces, but casualties from the blasts often also include civilians.
The United Nations says 2011 was the deadliest on record for Afghan civilians, with more than 3,000 killed in violence involving militants and NATO-led forces.
