In case anyone is in any doubt about the volatile situation many of our staff and stringers work under in Afghanistan I want to recount what happened on Saturday. Ahmad Nadeem was covering a demonstration that was sparked by the actions of extremist Christian preacher Terry Jones, who, according to his website, supervised the burning of the Koran in front of about 50 people at a church in Florida. The mood at the demonstration changed very quickly as the crowd sought a focus for their anger. Ahmad, our stringer in Kandahar was targeted. He was beaten with sticks, his gear smashed and his hand broken. Then an armed man instructed the mob to kill him. Ahmad fled for his life escaping into a nearby house where he successfully hid from the mob. Earlier in the day a suicide attack also hit a NATO military base in the capital Kabul, the day after protesters overran a U.N. mission in the northern city of Mazar-i-Sharif and killed seven foreign staff in the deadliest attack on the U.N. in Afghanistan.
