A German appraisal that Afghanistan remains "volatile" has rekindled a row over whether to reject asylum-seekers, the Deutsche Welle reported.

The Foreign Office appraisal made public Sunday by German news outlets said Afghanistan remained in a "tough establishment phase and, as before, in a volatile security situation" after decades of armed conflict, the report said.

Seizing on its wording, Pro Asylum said Germany's BAMF migration agency must re-examine tens of thousands of bids from Afghans previously rejected on the grounds that on return to home they would find safety in alternative areas.

Bavaria's Christian Social Union (CSU) — girding for a state election in October — on Sunday demanded a review of German policy since 2016 of expelling only those Afghans classified as offenders or as dangerous, or those who persistently hide their identities.

So-called fallback options for discriminated, threatened or persecuted persons seeking safe places depended centrally on whether they had social contacts at the local level, on their ethnicity, and on their financial situation, said the situation report distributed internally to German authorities last Thursday.

For women, the report said, it was hardly possible to switch to other regions without family connections. Without ethnic links, finding jobs was difficult in cities.

And the capacity of bigger centers to absorb returnees was complicated by the return of Afghans from Iran and Pakistan and those internally displaced, said the report.

Germany’s CSU General Secretary Markus Blume insisted Sunday that Afghanistan still had "stable regions" into which "rejected asylum applicants could be returned."

"We cannot talk repeatedly about more expulsions but then set the hurdles so high that these are not possible," Blume told the Bild am Sonntag newspaper.

Afghanistan needed "persons to work on its reconstruction," Blume asserted as Afghanistan approaches fresh elections.
