Germany has announced temporary border controls to curb irregular migration, a move that has sparked controversy among its neighbors.

Interior Minister Nancy Faeser declared the controls, citing threats from Islamist terrorism and cross-border crime.

The plan, which includes a model for increased rejections at the borders, has been notified to the EU Commission.

While North Rhine-Westphalia's Minister President Hendrik Wüst supports the measure, Poland's Prime Minister Donald Tusk has criticized it as "unacceptable" and plans urgent consultations with other neighboring countries.

The controls, set to begin on September 16 for six months, aim to manage migration more effectively, but have raised concerns about their impact on the Schengen Agreement and the potential for large refugee camps at EU borders.
