Greek authorities detained six foreigners for suspected human trafficking on Wednesday as the interim government announced new new measures to tackle a crisis that has seen hundreds of migrants and refugees arriving on Greek shores every day. Four Bulgarians and two Turkish citizens were detained in the northern Greek city of Thessaloniki for trafficking 103 migrants from Turkey to Greece, a police official said on Wednesday. The traffickers had charged the Syrian migrants 2,000 euros (1,469 pounds) per head to transport them to Greece and then on to Macedonia.
