The International Assistance Mission, a Christian development agency, has rejected Taliban claims that 10 of its staff killed in an attack in Afghanistan had been trying to convert Muslims.
It also categrorically rejected claims about spying and subversion made by the group claiming responsibility for the brutal summary executions.
"Our faith motivates and inspires us, but we do not proselytise. We abide by the laws of Afghanistan," Dirk R. Frans, IAM's executive secretary, said in a statement at a media conference in Kabul earlier this week.
The 10 workers - six US nationals, a Briton, a German and two local Afghan staff - were killed on 5 August 2010 as they returned from a trek through the Hindu Kush mountains, where they had been providing eye care to poor and remote communities.
The incident has provoked international outrage. The International Assistance Mission has also said that it will continue its humanitarian work, in cooperation with civil society groups.
Meanwhile, twenty religious organisations are calling for the US Congress and President Barack Obama to ensure a fair and thorough investigation into allegations of forced human experimentation by the Central Intelligence Agency on detainees after the 11 September 2001 terrorist attacks.
