WASHINGTON - The US Defence Department has disclosed that the Bibles sent by a US church to Afghanistan were confiscated and burnt by the military. Spokesman Lt Col Mark Wright said the Bibles printed in the two most common Afghan languages were seized on arrival at Bagram Air Base because the US military rules forbid troops from proselytising. The decision was made that it was a 'force protection measure to throw them away, because, if they did get out, it could be perceived by Afghans that the US govt or the US military was trying to convert Muslims, Wright told the CNN. He said military officers considered sending the Bibles back to the church but worried that the church might turn around and send them to a different organisation in Afghanistan. The situation came to light recently after Al-Jazeera aired a video in which a reporter suggested the US troops were being encouraged to spread Christianity. However, the military did not identify the church that supplied the Bibles.
