The vast majority of Syrian refugees arriving in Greece may be highly educated, including a significant number of students, according to new UN data.

AFP reports that the UN refugee agency (UNHCR) released a provisional profile of those who have made the treacherous journey across the Mediterranean Sea after fleeing Syria's civil war, based on questionnaires given to 1,245 people who landed in Greece between April and September.

The agency stressed that the data was not collected through random sampling and cannot be used to make general statements applicable to the entire Syrian refugee community in Europe.

But a full 86 percent of those who took the questionnaire said they had secondary school education or higher.

Sixty-three percent said they had left Syria in 2015, while 85 percent said they successfully made it to Greece on their first try.
