The National Socialist Underground or NSU (German: Nationalsozialistischer Untergrund) was a far-right German terrorist group which was uncovered in November 2011. So far, the following crimes have been attributed to the NSU: the National Socialist Underground murders, a series of murders of nine immigrants (eight Turks and one Greek) between 9 September 2000 and 6 April 2006; the murder of a policewoman and attempted murder of her colleague; the 2001 and 2004 Cologne bombings; and a series of 14 bank robberies. The Attorney General of Germany called the NSU a "right-wing extremist group whose purpose was to kill foreigners, and citizens of foreign origin".
On 4 November 2011, after a bank robbery in Eisenach, Uwe Mundlos and Uwe Böhnhardt were found shot dead in a mobile home, which was burning. Police said that the two set the vehicle on fire and killed themselves when their vehicle was found. In that caravan, the service pistol (HK P2000) of murdered police woman Michèle Kiesewetter was found. Some hours later on the same day, their flat in Zwickau, where the trio had lived under false identities, also was set on fire, and an explosion occurred. Beate Zschäpe, the alleged third core member of the terrorist group, is suspected of having caused that. She later turned herself in on advice from her lawyer.
