• It is not clear what the group plans to do once they reach the border.

A convoy of hundreds of people plans to head to the Texas border to stop migrants crossing into the country from Mexico.

The group, called "Take Our Border Back," is organizing on Telegram and now has more than 1,600 followers.

One of the group's organizers described them as "God's army" in a planning call, according to Vice.

"This is a biblical, monumental moment that's been put together by God," one organizer said, per Vice.

Another said: "We are besieged on all sides by dark forces of evil."

"Blessed are the peacemakers, for they shall be called the sons of God. It is time for the remnant to rise," they said.
