(5)The president of the European Commission Jean-Claude Juncker has said there is no need to change the EU’s policy on migration following the attacks in Paris. A Syrian passport found next to the body of one of the gunmen in Paris was registered to a refugee who had entered the EU last month via Greece. Mark Lowe reports from the Turkish resort of Bodrum where many make the journey to the Greek islands. "The authenticity of the passport is still unclear.(6)Frontex, the EU’s border agency, warned earlier this year that Syrian passports were being forged as they’re more likely to be accepted for shelter. But Greek officials say the passport was presented in Leros on October 3. The holder is likely to have reached the island from here in Bodrum,(7)one of the over 500 000 who have travelled from Turkey to the Greek islands this year, Leros among those receiving the highest volume."
