Moria

Although large numbers of refugees have been transferred to reception facilities on the mainland from overcrowded camps in the Aegean in recent days, hundreds more remain on the islands with a new cold snap expected later this week.

Around 300 migrants have been arrested following a riot in Bulgaria's largest migrant center in Harmanli, as Greece calls on European union member states to speed relocation efforts after a tragic accident killed two migrants in an overcrowded Lesbos camp, Voice of America reported on Saturday.

A 24-year-old woman and her toddler son are in critical condition in Athens hospital after suffering extensive burns in a deadly blaze at the Moria migrant processing center on the Aegean island of Lesvos, authorities confirmed on Friday.

Four Pakistani 17-year-olds were arrested on Wednesday, accused of gang-raping a 16-year-old boy in a refugee camp on Lesvos.

According to authorities, the incident occurred on Sunday morning at the overcrowded Moria camp and was recorded by the assailants on their cell phones.

Tensions were building on the Aegean island of Lesvos on Thursday, a day after an elderly man threatened refugees outside the Moria camp with a hunting rifle, as authorities continued with efforts to accommodate hundreds of migrants left homeless following Monday's fire at the camp.

Greece on Wednesday managed to find shelter for some 5,000 migrants on the island of Lesvos two days after a fire ravaged part of the main asylum seekers' camp, officials said.

But overcrowding remains an acute concern on the island, one of the epicentres of the European migrant crisis, they said.

The government on Tuesday put into motion the transfer of 91 unaccompanied refugee children from the eastern Aegean island of Lesvos to the Greek mainland, following a destructive fire at the island's main migrant processing center, or hot spot, at Moria.

Tents and prefabricated homes went up in smoke at a refugee and migrant processing center on the eastern Aegean island of Lesvos on Monday night, leaving hundreds without shelter.

New clashes between groups of refugees and migrants of different nationalities broke out on Monday evening inside the Moria hot spot in Lesvos, police said. Around 4,000 asylum seekers have escaped the camp in the Aegean island of Lesbos.

The blaze at the Moria camp has left a trail of destruction including damaged tents and housing units.

A rumour that 5 Pakistanis and 2 Moroccans died while being transported in a truck in some Greek port, resulted in about 200 Pakistani migrants breaking out of the Moria hotspot in Lesvos, and marching on the city of Mytilene in protest. The Pakistanis smashed two cars of employees outside the reception centre on their way to the city centre, about 8km from the hotspot.
