Friedrich Merz, the conservative front-runner in the race for Germany’s chancellorship, called for a radical overhaul of the country’s migration policy including permanent border checks. The comments come after an asylum seeker from Afghanistan was taken into custody over a fatal stabbing of a two-year-old child and a man in a park on Wednesday.

However, some Germans blame the CDU, and in particular Merz's predecessor and longtime chancellor Angela Merkel, for encouraging the large-scale influx of asylum seekers and migrants, mostly from the Middle East and Afghanistan, in 2015.
