Up to 100,000 decisions to grant asylum to migrants in Germany will be re-evaluated after a soldier was granted asylum through a fake identity as a Syrian refugee, German Interior Minister Thomas de Maiziere said Wednesday.

Franco Albrecht, a 28-year-old German soldier, posed as a refugee, and managed to secure a spot at a refugee home and receive state financial aid. German authorities allege he was part of a far-right plot to assassinate political figures and then blame refugees.

"This is unfortunate, and this must lead to further consequences," Maiziere said, calling for better quality control.

Authorities will now review 100,000 successful cases from 2015 to 2016, in particular cases of young men between the ages of 18 and 40.

"This measure is a very extensive, very important and very necessary for security," Maiziere said.

According to German interior minister, Albrecht's case was isolated and no "comparable case" has been found.
