• A fire destroyed almost the entirety of Europe's largest refugee camp on the Greek island of Lesbos.
• More than 12,000 are now displaced, the BBC reported.
• Greek authorities said the fire most likely started by camp residents who were "dissatisfied" with a coronavirus lockdown, CNN reported.
• Thirty-five people at the camp tested positive for COVID-19 this week.
• The camp is known for its overcrowding and unsanitary conditions.

The overcrowded Moria refugee camp in Greece was set ablaze on Tuesday night displacing the more than 12,000 migrants being housed there.

Greek authorities said the fire was most likely started by camp residents who were "dissatisfied" with lockdown measures implemented to curb the spread of the coronavirus, after 35 people tested positive for COVID-19 this week, CNN reported.

Non-governmental organizations told the Guardian that the situation is dire and more tragedy is unfolding as the camp still burns.

Annie Petros, head coordinator of the charity Becky's Bathhouse, told the Guardian that police prevented her from taking injured people to the hospital while she was driving them away from the fire.

"When we saw there was a fire we drove as fast as we could with water to the camp, intending to take sick people to hospital. I can't describe properly the scene we saw. There were streams of people, thousands of them, walking away from the camp. They were totally silent, terrified and traumatized, walking through thick smoke and the awful smell of burning plastic," Petros told the outlet.
