The UN refugee agency says it's "deeply concerned" about new US restrictions on asylum-seekers, saying it will put vulnerable families at risk.
The UNHCR comments came after the Trump administration said it would end all asylum protections for most migrants who arrive at the US-Mexico border.
According to the plan, migrants who pass through another country - in this case, Mexico - on their way to the United States will be ineligible for asylum.
The rule is expected to go into effect Tuesday and would affect many refugees fleeing violence and poverty in Central America.
The UNHCR says the rule overly restricts the right to apply for asylum, and threatens the right not to be sent back to countries where people could face persecution.
