A motorbike bomb killed on Wednesday four civilians and injured ten others in an Afghan town on the border with Pakistan.

The bomb was remotely controlled in the town of Spin Boldak in Kandahar province, with officials blaming the attack on the Taliban.

"There was a motorbike bomb blast against border police in Spin Boldak. Four civilians, one of them a woman, were killed and 10 others were injured," said Janan, a rapid-reaction police unit commander who uses only one name.

The interior ministry confirmed the deaths and blamed the blast on the "enemies of Afghanistan" -- a reference to the Taliban.

Afghan leaders accuse Pakistan of secretly helping the Taliban by providing hideouts and training facilities in secret camps across the border.

Pakistan denies the accusations and says it has lost around 3,000 soldiers fighting a local Taliban insurgency in the northwestern border areas with Afghanistan.
