Arpineh told the BBC she was held in a freezing, brightly lit room with 28 other women for three days. They survived on snacks and one bottle of water a day, she says, the women huddling together for warmth, and sleeping on the floor.

“I’m not deportable to any country,” Arpineh told the BBC from the detention facility.

But that hasn’t stopped immigration officials in the past. In February, a group of Iranian Christians who had just crossed the border from Mexico were deported - but to Panama, not Iran.

As a German I am shocked. It actually looks like it’s only a matter of time until they go the “easy” way and simply fill these rooms with gas.
