Migrants resorting to prostitution in Athens
A BBC investigation has found young migrants, including teenagers, are resorting to prostitution in the Greek capital, Athens.
Authorities say nearly 60,000 migrants are currently in Greece scattered in various camps across the Aegean islands and the mainland.
Most are keen to get to northern Europe but new border rules have left them stranded, with no legal means of earning money.
