Swedish police say that a female worker at a shelter for youth and unaccompanied minors was stabbed to death at the center in southwestern Sweden. Police spokesman Christer Fuxborg says that two people were holding down the male suspect when police arrived on the scene. The Belgian government says that because Greece is too weak to guard its own borders, it should face an EU "sanction mechanism" under which the rising number of refugees entering the country would effectively be forced to stay there. Belgian Migration State Secretary Theo Francken told the VRT network that "the Greeks now need to bear the consequences" if internal border controls within the Schengen area, which is supposed to be a passport free zone, are extended for two years, as is currently discussed. A Greek minister has angrily blamed European Union member states for failing to send Athens enough manpower and ships to help it tackle the migrant crisis and for not living up to pledges to relocate migrants. Immigration Minister Ioannis Mouzalas told reporters on the sidelines of an EU meeting in Amsterdam on Monday that sending officers from the EU border protection force known as Frontex to neighboring Macedonia in an attempt to halt migrants there would be illegal. In a joint statement after the meeting, the two sides acknowledged there is a "need to exert huge effort" to counter the flow and that Ankara needs to do more to fight smuggling networks and the influx of migrants who are not eligible for asylum. Germany's vice chancellor is dismissing a proposal by a senior member of Chancellor Angela Merkel's party to manage the migrant influx by setting up centers at borders from which refugees would be allowed into the country according to daily quotas. European Union justice and interior ministers have started urgent discussions on how to tackle the migrant crisis amid the stream of new arrivals and continuing disagreements over how to seal off borders.
