ATHENS (Reuters) - At least 13 suspected members of an international criminal organisation smuggling undocumented migrants to other European countries have been arrested, Greek authorities said on Friday.
An operation to dismantle the ring was under way on the island of Crete, and Britain's National Crime Agency was also involved, police said.
Crete, Greece's southernmost island, lies north of Libya and Egypt. The head of the local coastguard, Dimitris Saitakis, told reporters at least 13 suspected smugglers had been arrested, as well as 131 migrants hiding in caves or warehouses.
"This is a strong blow to organised crime on Crete," Saitakis said, adding that he expected the number of arrests to rise "dramatically".
Greek media said those arrested were migrants from Egypt and Pakistan and Syrian refugees.
More than 60,000 migrants and refugees are stranded in camps in Greece by border closures across the Balkans which have halted their onward journey to northern and western Europe.
For refugees, the only legal way out of Greece is through an EU relocation programme to other member states, which has been progressing slowly. Those not eligible for asylum face deportation.
On Thursday, the coastguard said it had arrested three migrants, one of whom was hiding in a suitcase, when they tried to board a ferry from the eastern Aegean island of Lesbos to the mainland.
