Suspected Taleban militants have shot dead an Afghan aid worker in a mosque in southern Afghanistan, officials say.
The victim was shot in the head inside the mosque in Lashkargah by two men travelling on a motorbike, Helmand's deputy governor said.
The dead man, identified as Mirwais, had worked as an engineer for a Bangladeshi aid group.
No group has said it carried out the attack but officials have blamed the Taleban for such killings in the past.
Increased violence in southern and eastern parts of Afghanistan has made it difficult for aid organisations to operate in those areas.
Insurgency-related violence left more than 1,400 people dead in Afghanistan in 2005 - the country's bloodiest year since US-led forces ousted the Taleban in late 2001.
