Very little is known about the group, Apo's Youth Revenge Brigades.  Only one attack has been attributed to them.  On March 10, 1999, the group claimed responsibility for the firebombing of a car belonging to a member of the Nationalist Action Party of Turkey.  There were no injuries, but the vehicle was completely destroyed.  Apo's Youth Revenge Brigades claimed that more attacks would be forthcoming. <p><p>The attack appeared to be a reprisal for the February 1999 arrest of Abdullah Ocalan (whose nickname is "Apo" or "Uncle"), the founder and leader of the Kurdish Workers' Party (PKK).  Following Ocalan's arrest, violence erupted throughout Turkey.   It is unclear whether the Apo's Youth Revenge Brigades acted autonomously or with the support of the PKK.  It is also unclear whether the widespread pro-Ocalan violence that erupted in March 1999 was spontaneous or coordinated by the PKK or another organization.

No attack has been attributed to Apo's Youth Revenge Brigades since March of 1999.

The founding of the terrorist group, April 19 Movement (M-19), was precipitated by the outcome of a Colombian presidential election.  Former Colombian dictator-cum-populist  Rojas Pinilla ran for the presidency in 1970 as a member of the political party, National Popular Alliance (ANAPO).   Under the banner of populism, ANAPO enjoyed wide support among the urban poor.  On May 19, 1970, Rojas Pinilla lost the presidential election, coming in a close second.  <p><p>While ANAPO officially rejected violence as a retaliatory answer to the loss, some members of the group broke ranks.  Rather than accept the results of the closely contested election, these individuals, now calling themselves M-19, decide to embark on a violent terrorist campaign that continued for two decades and cost countless lives.  M-19, taking its name from the date of Rojas Pinilla's presidential loss, professes support for the poor of Colombia.  Unlike earlier groups, such as the FARC and ELN, M-19 was not founded in the shadow of the Cuban socialist revolution of 1959.  Instead of professing firm support of communist ideology, M-19 followed a more generalized leftist ideology of support for the poor and reform within the Colombian government.
