Dozens of people have gathered outside one of Southern California's main Border Patrol stations in the town of Murrieta, to protest the arrival of illegal immigrants that were flown from Texas to San Diego Tuesday.
A plane carrying the immigrants landed in San Diego shortly after noon, who were then transferred to buses. In Murrieta, residents lined a street carrying American flags and signs, one of which read, "Return to Sender."
The trio of buses carrying about 140 immigrants who entered the country illegally arrived at the Border Patrol facility just after 2 p.m.. Intent on voicing their opposition to their arrival, a group of protesters, many waving American flags, moved into the street and blocked the buses from passing.

At 2:30 p.m., the buses began to back away from the protesters and the facility, and headed back south on Interstate 15, eventually winding up at a border station in San Ysidro in San Diego County.
The buses' departure marked a small victory for the roughly two dozen protesters who had gathered, at least for now. Officials said more migrants could be brought to Southern California in as soon as 72 hours.
A small band of immigrant supporters also gathered outside the Murrieta facility, but they were largely drowned out by protesters.
At around the same time, U.S. Immigration and Customs Enforcement (ICE) released an update to Murrieta Patch on the situation and what's expected to happen once the people are eventually "processed" in Murrieta.
"Once DHS personnel in Murrieta finish processing the migrants, those who are being released will be transported by LA [Enforcement and Removal Operations] to a 'transition center' in Riverside County that is being set up by a faith-based organization," ICE Spokeswoman Virginia Kice said in an email.
According to Kice, ICE will not be immediately releasing the name of that organization, nor the specific city, where the people will be taken for the transition center.
"At the transition center, the organization’s volunteers will assist migrants with obtaining commercial transportation to their final destinations and help them contact family members and relatives," she said, adding that the cost of those transfers will not be paid for by the government, but rather by the migrants or the faith-based organization and consular representatives.
Kice said that "in most instances," the final destinations of the migrants will be outside Southern California. In the meantime, though, the unnamed group helping them out will also get them set up with food, clothing and any other essentials.
U.S. Immigration and Customs Enforcement officials said Monday the migrants are mostly "adults with children" and were among tens of thousands of citizens of Central American countries who have poured into the United States via Texas this year.
The Border Patrol's Rio Grande Valley sector has been overwhelmed by the arrivals, prompting the U.S. Department of Homeland Security to seek other locations to send them until their cases can be assessed.
