German officials concerned over Taliban migrants

German officials have voiced concern over the possibility of thousands of former Taliban fighters having entered the country over the past two years among an influx of more than a million migrants and refugees.

Germany's Federal Office for Migration and Refugees (BAMF) informed the security officials that thousands of migrants had identified themselves as former Taliban insurgents during the asylum application process, Der Spiegel magazine reported on Saturday.

It stated that at least 70 Afghan men were being investigated by Germany's over-stretched chief federal prosecutor, though it was not clear whether all of them were suspected of being active Taliban militants.

The German government has recently come under fire for allowing the migrant influx, especially after several militant attacks were linked to the migrants last year.

Germany has, however, been deporting groups of rejected Afghan asylum seekers in the recent months.
