In 1971, a group calling themselves the People's Revolutionary Front (PRF) claimed responsibility for two bombings at the headquarters of U.S. oil companies in Manila, Philippines. The bombs killed one and caused extensive damage. A note at the site of the bombings claimed responsibility for the attacks in the name of the group and said "this is the anger of the Filipino people against American imperialism."  <P><br /><br />Although very little is actually known about the People's Revolutionary Front, these bombings were one of several terrorist incidents that targeted U.S. interests in the Philippines in the early 1970s.  Most of these attacks were unclaimed, but there is widespread speculation that they were the work of members or affiliates of the nascent New People's Army (NPA), the military wing of the Communist Party of the Philippines (CPP).   The NPA was founded in 1969 and has been dedicated to overthrowing the Filipino government and instituting a communist state since that time.  The group has been responsible for numerous attacks on U.S. interests in the past, lending to speculation that the PRF could have been somehow related to the NPA.  <P><br /><br />While it is possible that People's Revolutionary Front was an alias for the NPA, or supported a similar communist ideology, there is no concrete proof to support this claim.  It is also possible that the PRF was simply anti-American, and did not espouse a particular political ideology.  The United States was a former colonial ruler of the Philippines and maintained a significant military and economic presence on the islands at the time of the attacks (the United States has maintained this presence to the present day).  Furthermore, in 1971 the Philippines were ruled by Ferdinand Marcos.  Heavily supported by the United States, Marcos had engendered a great deal of public anger over his corrupt rule.  The U.S. support for Marcos certainly could have motivated the People's Revolutionary Front to attack U.S. targets.  Lending credence to this theory is the fact that the PRF's claim mentioned U.S. imperialism, but did not overtly espouse any communist or socialist ideology.  <P><br /><br />In any case, the People's Revolutionary Front was never heard from after the bombings.  The group could have possibly merged with the NPA, or simply de-activated and pursued non-violent opposition to the U.S. presence in the Philippines.<br />
