Al-Jazeera TV reported last week that it received an audio statement from al-Qaeda’s North African branch claiming responsibility for the June 23 shooting death of an American aid worker in Nouakchott, Mauritania. According to the message—the authenticity of which has not been verified—the Islamic Maghreb said group members murdered Christopher Leggett, 39, for allegedly trying to convert Muslims to Christianity.

 

The Mauritania region has witnessed an increase in extremist violence in recent years, including the 2007 murder of a group of French picnickers. Leggett had lived with his wife and four children for six years in the moderate Muslim nation where he taught at a computer science and language school in a poor neighborhood of Nouakchott.
