Christians working in Greece's most notorious asylum detention centre have tried to convert some of the Muslim detainees, who have been held under the terms of the EU-Turkey migration deal.
On at least two occasions in recent months, aid workers have distributed conversion forms inside copies of Arabic versions of the St John's gospel to people held at the Moria detention camp on Lesbos.
The forms, seen by the Guardian, invite asylum seekers to sign a statement declaring the following: "I know I'm a sinner ... I ask Jesus to forgive my sins and grant me eternal life. My desire is to love and obey his word."
