More than 900000 refugees have arrived in Europe since January

Four suspected smugglers were also detained while four boats and six motors were seized.

Pierre Moscovici, EU commissioner for economic and financial affairs, said: “Following the horrific terrorist attacks on their country this year, the European Union is more determined than ever to stand by the people of Tunisia”.

It was not clear if Monday’s sweep was directly related to the Turkish commitment to help contain the flow of migrants and officials could not immediately be reached for comment.

He adds, “Asylum seekers fleeing most countries today can not obtain effective refugee protection in Turkey”. The International Organization on Migration estimates that more than 220,000 migrants arrived in Greece by sea in October alone and more than 220 died in the waters between Turkey and Greece in that same month.

The suspects are believed to have set up headquarters in Greece, where migrants – either in Turkey or on their way to Greece – would contact them for assistance with their journeys to northern Europe.

A Luxembourg government spokeswoman said Asselborn’s latest visit to Greece was to check on the functioning of EU-agreed measures, such as processing migrants through “hot spots” for identification. The European Union is attempting to prevent their travel to the bloc by giving Turkey money to provide for decent refugee living conditions.

Women and children react as they sit on shore after arriving with other migrants and refugees on the Greek island of Lesbos by crossing the Aegean Sea from Turkey on November 26, 2015.

Another concern is that Turkey will try to restrict the flow of people entering the country, since it is unable to let out the millions it has already in the country.

Ghani says to keep Afghans in the country “people need three things: first they need jobs, second they need vocational training to be able to have jobs and third they need housing”.

The EU-Turkey deal is also unlikely to deter desperate refugees seeking sanctuary in Europe.
