The media added that 10,168 refugees are residing in official centers for migrants built in the Attica region in the suburbs of the Greek capital, while 5,423 are living in makeshift camps.
It comes a day after Greece's Center for Disease Control and Prevention (KEELPNO) urged the government to close all reception centers for migrants in the country following official visits by its inspectors to 16 such centers which were all deemed to be a public health risk.
Greece is one of the most popular transit routes used by refugees from the Middle East and Northern Africa to reach Northern and Central Europe. More than 1.8 million migrants arrived in the European Union in 2015, according to the EU border agency Frontex.
On July 22, the European Commission allocated an additional 82.6 million euros ($91 million) to Greece to tackle the increased flows of undocumented migrants and refugees. Moreover, 58.4 million euros are given to the Greek Ministry of Defense to provide migrants with urgent shelter, accommodation, catering, health care and transportation, it was note in the statement.
