Trump administration to allow longer detention of migrant families

Migrant families who cross the southern border of the US illegally could be detained indefinitely under a new regulation announced by the Trump administration.

It replaces an agreement that set a limit on how long the government could hold migrant children in custody.

The move, announced by acting homeland security secretary Kevin McAleenan, is due to come into effect in 60 days.

Mexico has expressed concern and said it would consider legal action.
