Summary: At least 10 people have been killed and 83 injured in the southern Afghan city of Kandahar, on a second day of violent protests over the actions of extremist Christian fundamentalist preacher Terry Jones, who supervised the burning of a Quran in front of about 50 people at a church in Florida on March 20. The new violence came one day after protesters overran a U.N. mission in the northern city of Mazar-i-Sharif, killing seven foreign staff in the deadliest attack on the U.N. in Afghanistan. … One-year retrospective: One year ago today, on April 3, 2010, Aubrey Immelman reported that the FBI was warning police across the country that the call of an anti-government group — a “sovereign citizen” group called Guardians of the Free Republics — to remove governors from office could provoke violence.
