A Syrian man set himself on fire at a migrant camp on the Greek island of Chios on Thursday in despair over his bid to gain asylum, the Greek news agency ANA reported.
Video footage, posted on Twitter by the BBC's Greece correspondent, showed a young man holding a petrol can and addressing camp residents, and then catching fire as a policeman approached.
The unidentified man was rushed to hospital with burns over 90 percent of his body, ANA said. The policeman who tried to save him was also hospitalized with burns.
Thousands of people, many of them Syrians fleeing war, are stuck in Greece's Aegean islands as a result of an EU-Turkish agreement that curbed the influx of migrants to the European Union.
Most of them have filed for asylum to avoid being sent back to Turkey, but these applications take months to handle. Humanitarian groups have repeatedly sounded the alarm over declining morale in their camps.
In a separate incident, Greek police said Thursday they had arrested a people trafficker who imprisoned 23 South Asian migrants for a week in a bid to blackmail their families into paying money for smuggling them into Greece.
The 26-year-old Greek national was demanding between 1,500 and 3,000 euros ($1,600 to $3,200) a head. The migrants had only made an up-front payment.
Police were alerted by a migrant who complained that his brother and a nephew were being held in the warehouse in Menemeni, a small town near the northern city of Thessaloniki, a police statement said
