Sweden's minister of justice, Morgan Johansson, said his government will challenge Hungary in court unless it starts taking back asylum seekers from other EU countries. The European Commission will send a delegation to Hungary to examine reasons for the dispute. Earlier this month, ministers from Denmark, Finland, Iceland, Norway and Sweden wrote to the EU executive complaining that Hungary is not abiding by the Dublin Regulation, which says refugees should seek asylum in the first EU country they enter. Over 1 million people entered Europe last year, and many were first registered in Hungary.
