Little is known about Abu Nayaf al-Afghani, an al-Qaeda affiliated terror group that operates in Spain. The group is associated with al-Qaeda and its European cells, though the extent of the group's operational component is unclear. In April 2004, Abu Nayaf al-Afghani faxed a statement to a Spanish newspaper that claimed responsibility for an unsuccessful train bombing against a high speed train en route from Madrid to Seville.  Several days later, the same group left a video tape by a mosque in Madrid, claiming responsibility for the infamous March 11 Madrid train bombings, despite the fact that this bombing occurred almost one month prior to Abu Nayaf al-Afghani's claim.  Needless to say, the length of time between the Madrid bombings and Abu Nayaf al-Afghani's claim has cast doubt on its authenticity. The bombings on March 11, 2004 killed 191 people and wounded over 600. Ten bombs were planted and detonated nearly simultaneously on a busy commuter rail line south of Madrid. <P><br />Other sources attribute the March 11 attacks to the group Abu Dujana Al-Afghani Ansar Al-Qaeda Europe, which appears be an alias for Abu Nayaf al-Afghani. A separate Al-Qaeda linked organization, the Abu Hafs al-Masri Brigade, also declared responsibility for the Madrid attacks, and although it faces similar questions about the validity of its claims, it is generally regarded by authorities as having carried out the attacks.  While Abu Dujana Al-Afghani Ansar Al-Qaeda Europe and Abu Nayaf al-Afghani are likely the same operational group with aliases, the Abu Hafs al-Masri Brigade is probably an operationally distinct group loosely aligned with Abu Nayaf al Afghani.  All of these groups are thought to share al-Qaeda's ideological convictions, though the extent to which they coordinate their actions is not fully known.  <P><br />Abu Nayaf al-Afghani's political goals are less mysterious. The group seeks mainly to end Spanish support for American led efforts in the war on terror, citing "...Spanish...aggressions against Muslims in sending new troops to Iraq and announcing its intention to send new units to Afghanistan." The group's moniker contains two such references, as "Nayaf" refers to the Iraqi holy city of the same name ("Najaf" in Romanized Arabic), while "Afghani" is undoubtedly an allusion to American operations in Afghanistan. <br /><br />
