The bombing across from the U.S. Embassy in March suggested that Sendero Luminoso, the Shining Path terrorist group, was gaining strength after being essentially eradicated in the 1990s. Now the State Department has announced that it has indications that the group may be planning actions against Americans or American interests on or around the May 17 anniversary of the group’s founding in 1980. Such attacks would be most likely in a place where large groups gather or where Americans or other foreigners tend to congregate. Avoid these areas in mid-May.
