SAN DIEGO -- A group of activists gathered in San Ysidro Friday to begin a nearly monthlong series of demonstrations at locations along the U.S. border with Mexico to call for an immigration overhaul.

Organizers of "Migrant March II," led by immigrant rights activist Enrique Morones, said the event is intended to rally support in favor of "fair immigration reform and demilitarization of the border."

"There is not one documented case of a person crossing the U.S.-Mexican border that committed a terrorist act, not one," Morones told news media. "There's three from Canada. Three different cases. Yet, the National Guard is sent to the Mexican border."

The group plans to drive a caravan of vehicles from San Diego to Brownsville, Texas, and back, stopping at border cities along the way. The demonstration will culminate with an "All People's Immigration Hearing" in San Diego on Feb. 17.
