ATHENS (REUTERS) - A ferry carrying 45 migrants left the Greek island of Lesbos for Turkey on Friday (April 8), the second such journey carried out under a controversial EU deal to stem mass irregular migration to Europe.

A second boat carrying a larger group was scheduled to leave the island later in the day, state TV reported. Those who left early on Friday were from Pakistan, it said.

The first group of 202 migrants to be returned, most of them from Pakistan and Afghanistan, were sent back to Turkey on Monday.

At the port of Mytilene, at least two activists jumped into the water close to the small ferry, dangling from the heavy chain of the anchor and flashing the 'v' sign for victory. They were hoisted out of the water by the Greek coastguard.

Under the EU-Turkey deal, Ankara will take back all migrants and refugees, including Syrians, who enter Greece through irregular routes in return for the EU taking in thousands of Syrian refugees directly from Turkey and rewarding it with more money, early visa-free travel and progress in its EU membership negotiations.
