ENCINITAS, Calif. -- A group of anti-illegal immigration activists squared off in Encinitas Saturday against a pro-immigration group supporting day labor workers who gather at a popular roadside spot, a sheriff's sergeant said.

Members of the Encinitas Citizens Brigade took to the streets on Encinitas Boulevard -- between Interstate 5 and Vulcan Avenue -- to clear the area of day laborers waiting for pickups from prospective employers, sheriff's Sgt. Mark Varnau said.

Immigrant day laborers have for years gathered near a Shell station and shopping center to wait for job offers from passing motorists.

The Citizens Brigade -- which arrived at about 8 a.m. -- was joined by members of the San Diego Minuteman Project, Varnau said.

A counter-protest was mounted by the pro-immigration activists.
