Children as young as 10 have attempted suicide in a notorious refugee camp on the Greek island of Lesbos, a humanitarian organisation has warned.

More than 8,000 refugees and migrants are living in filthy conditions in Moria refugee camp, which was designed to accommodate around 3,000 people.

Fights regularly break out between different nationalities, many people are suffering from depression and now Medecins Sans Frontieres says it is dealing with children as young as 10 contemplating suicide.

"It's something we're seeing constantly," Luca Fontana, Lesbos co-ordinator for MSF, told the BBC.

Aid agencies have appealed to the Greek government and the UNHCR to transfer children and their parents to camps on the mainland.

"Despite the fact that we push to move these children to Athens, as soon as possible, it's not happening. Those children are still here," said Mr Fontana.
