MEXICO CITY (AP) -- One of Mexico's drug cartels promises there'll be no violence during the Pope's visit next weekend.
An official in Guantajuato state says at least 11 banners signed by The Knights Templar gang were found in five municipalities, including the city of Leon, where the pope begins his trip Friday.
He says the banners carry messages about "a sort of truce for peace" during Pope Benedict's visit.
In February, The Knights Templar put out banners warning rival gangs to stay away and not create trouble during the pope's stay.
Benedict is scheduled to visit Guanajuato from Friday until Monday.
Earlier Sunday, Mexican authorities said they had found 10 severed heads dumped outside a slaughterhouse in a town in northern Guerrero state.
Police still are searching for the bodies.
