Due to its proximity to the Turkish mainland, Lesbos is one of the Greek islands most affected by the European migrant crisis that started in 2015. Refugees of the Syrian Civil War came to the island in multiple vessels every day. As of June 2018, 8,000 refugees were trapped when a deal between Europe and Turkey removed their route to the continent in 2016. After that, living conditions deteriorated and the possibility for movement on to Europe dimmed. Moria Refugee Camp was the largest of the refugee camps and held twice as many people as it was designed to accommodate.
