The clergymen, part of a 29-member delegation of the Chicago-based
                  Pastors for Peace group, were briefly detained Saturday when they traveled
                  to El Bosque.

                  In recent months, the Mexican government has waged a campaign against
                  foreign involvement in the political unrest that has followed a brief rebellion
                  almost five years ago by the Zapatista National Liberation Army. More than
                  150 foreigners have been expelled this year for alleged political activity.

                  Andres Chao, spokesman for Mexico's immigration institute, said the
                  Americans were told to leave by Friday under new regulations that require
                  foreign observers or humanitarian workers to list places they intend to visit in
                  their visa application.

                  Lucius Walker, president of Pastors for Peace, said the five were on their
                  way to the town of Union y Progreso with a truckload of food, but took a
                  detour to a village they hadn't listed on their visas because the road became
                  impassable.

                  Chao said the pastors were detained for their own safety because the area is
                  near the zone of influence of Zapatista rebels. He said they would be
                  allowed to return to the country.

                  Police also detained three Italian tourists in northern Chiapas state and
                  accused them of participating in Mexican politics, which is illegal under a
                  tourist visa.
