QUITO, Ecuador (AP) -- An unknown Marxist group has claimed
                   responsibility for a wave of attempted mail bombings directed at journalists
                   and political leader. It was the third group to say it was behind the violence.

                   Several news agencies received pamphlets late Thursday and early Friday
                   from the group calling itself the People's Liberation Army, claiming
                   responsibility for the bombings that began 10 days ago.

                   Newspapers published accounts of the document in which the group
                   described itself as a "political-military Marxist movement that has as its goal
                   the implementation of socialism" in Ecuador.

                   The mail bombing campaign started on Feb. 16, when a television news
                   director opened a booby-trapped video cassette and suffered minor wounds
                   to his hands, chest and face.

                   A string of attempted mail bombings followed, targeting other journalists, a
                   Social Christian party congresswoman and an evangelical Indian leader, as
                   well as others who authorities have refused to identify.

                   Two other groups -- the National Liberation Army of Ecuador and the
                   People's Combatants Group -- claimed responsibility for mailing the
                   explosives. Their motives were not immediately clear.
