On Monday, around 1,000 people remained in Piraeus, with the number reaching zero after the last 426 people left the port on Wednesday, heading to reception centers across the country, according to the coordinating body.
A total of 57,027 refugees were registered by the body on Thursday morning. The last 24 hours saw the arrival of 108 refugees in Greece, with 35 arriving on the island of Lesbos and 72 arriving on other islands.
The European Union has been struggling to manage a massive refugee crisis, with hundreds of thousands of people leaving conflict-torn countries in the Middle East and North Africa to escape violence and poverty and seeking asylum in Europe. The EU border agency Frontex detected over 1.83 million illegal border crossings in 2015, in contrast to some 283,000 in 2014.
