Protests against illegal immigration planned for more than a dozen border crossings in the southwest over the weekend were called off because of threats, evidently from Mexican drug cartels.

The protests, which were titled "Shut Down All Ports of Entry," were scrapped because of what one organizer, Stasyi Barth, attributed to threats and worrisome messages directed at the protesters.

"If you attend, you are not just putting yourself in danger, but the law enforcement officers, as well," Barth wrote, Reuters reported. "Risking anyone's life is not worth it!"

The intent of the protest was to stop incoming and outgoing traffic at border crossings in Texas, New Mexico, Arizona and California to express anger over the Obama administration's immigration policy.

Another one of the event's organizers, Rob Chupp, suggested to the wire service that Mexican drug cartels were behind the threats.

Reuters added that U.S. Customs and Border Protection said it was working with police departments in those areas to address the possibility of violence at the locations where the protests had been planned.
