At least 15 people were injured and taken to hospital after huge clashes and altercations last night between migrants of Afghan, Iraqi, and Arab descent at the Moria refugee and migrant camp at Moria, on the island of Lesvos.

According to the state run Athens and Macedonia News Agency, about 15 injured migrants were taken to hospital. Two people were stabbed with a knife, one of whom had a serious wound to in the chest and was placed in the surgical unit.

Dozens of migrants were wounded in rock battles as the clashes raged for hours, between about 10pm Tuesday night until 4am today, with migrants setting fire to about 10 tents in which those involved in the altercations were living, and migrants reportedly blocked the fire brigade from entering the camp area.

The clashes ended after protracted efforts by a strong police contingent that used flares and tear gas to break up the crowds.

Many migrants were rounded up by police, who arrested two of the individuals.

Clashes, though more limited, have become a daily affair at the Moria Camp, where the dreadful conditions fuel the unrest.

About 6,500 refugees and migrants reside at the Moria camp, which has a maximum capacity for 2,300 people. They reside in summer tents and lack heating and adequate clothing in many cases.

According to the asylum bureau, it takes over two months for officials to process refugee asylum applications.
