NNA - Germany's main opposition leader demanded a sweeping overhaul of migration policy and permanent border controls on Thursday, a day after an Afghan asylum seeker was arrested for a deadly knife attack targeting children weeks before federal elections.

Friedrich Merz, who is likely to become chancellor after the Feb. 23 vote, said the attack, which killed a two-year-old boy and an adult passerby, could not become the new normal, saying all "illegal immigrants" should be turned away at the border.--Reuters
