(CNN) -- Scandinavia's humanitarian generosity in the 1990s appears to have had some unintended, and unwelcome, consequences, as dozens of young ethnic Somalis living there have embraced jihad, returning to the Horn of Africa to join the al Qaeda affiliate Al-Shabaab. Norway's Intelligence Agency PST is still investigating whether one of the attackers at the Westgate Mall in Nairobi had lived in Norway. The 23-year old had come to Norway with his family at the age of nine as a refugee, but according to Norwegian media had become unsettled after being unable to find work and begun to frequent jihadist websites.
