Militia detains migrants at gunpoint along the US-Mexico border
A video has emerged of armed right-wing militia members stopping over 300 migrants as they cross the Mexico border into the US state of New Mexico.
The group calls itself the United Constitutional Patriots, and are seen in the Facebook clip standing over migrants sitting on the desert ground.
The group's actions have been condemned by civil liberties groups and New Mexico state officials.
The militia supports President Donald Trump's plan for a border wall.
The incident comes amid a spike in border crossings, despite White House efforts to stem the influx.
The video, posted to militia member Jim Benvie's Facebook page, shows a large group of migrants who were said to have just crossed the border near Sunland Park, New Mexico, being detained by the armed vigilantes on 16 April.
The migrant group, which contains many women and children, are seen sitting and squatting in the darkness and squinting up into the militia's spotlights.

Before Border Patrol agents arrive to take custody of the migrants, a woman narrating the video tells a man who appears to be a militia member "don't aim the gun" in the direction of the families.
Mr Benvie, a spokesman for the United Constitutional Patriots, told the New York Times the group has been camping in the region for the past two months and plans to stay until Mr Trump succeeds in building his controversial border wall.
