BERLIN: German rights groups took to the courts Friday on behalf of Afghans who were offered refuge by Berlin but are now caught between Chancellor Friedrich Merz's immigration crackdown and a wave of deportations from Pakistan.

Refugee support groups filed cases against Foreign Minister Johann Wadephul and Interior Minister Alexander Dobrindt, accusing them of "abandonment and failure to render assistance" to Afghans who were previously promised asylum in Germany.

The group Pro Asyl said Pakistan had detained hundreds of Afghans this week in an escalating series of arrests and deported 34, placing them at risk of "arbitrary imprisonment, mistreatment or even execution" in Taliban-ruled Afghanistan.

"We came to Pakistan one year ago because of the promise of the German government," a 27-year-old Afghan women's rights activist told AFP, asking not to be named for security reasons.

"In the last few days that the police have been searching for us, my children and I have become sick," said the mother-of-two, who added that she was "terrified and anxious" after several friends were arrested.
