A day after a fire broke out at a refugee hot spot which left hundreds of people without shelter, the Greek government pledged to take immediate measures to improve the situation.

A ship is to be leased to operate as a floating hot spot at the port of Mytilene until the Moria accommodation center is fully functional again, the Ministry of Citizen Protection and the General Secretary of the Aegean and Island Policy announced on Tuesday.

Refugee and migrant families are the priority, the General Secretary of the Aegean and Island Policy Giannis Giannelis told Xinhua.

"The ship will have a capacity of over 1,000 people and will be used as a hostel in order for the situation to be eased, after yesterday's incidents," Giannelis said.

In addition, extra police forces will be sent to Lesvos, he said.

People were forced to flee Moria and many spent the night in the streets without shelter or food, when a fire broke out during clashes among refugees of different nationalities in the hot spot on Lesvos island.

The fire spread through the camp and destroyed 50 tents and three containers, including personal belongings. Nobody was hurt by the fire.

Dozens of people escaped through small openings in the fence.

Most of them left all their personal belongings behind and some even walked to reach the city of Mytilene.

The Greek government is seeking ways to decongest all the eastern Aegean islands which continue to receive immigrants and refugees, Giannelis added.

More than 10,000 people out of the 60,000 currently stranded in Greece, according to data released on Tuesday from the North Aegean Regional Police Department, have remained trapped on Lesvos, Chios, and Samos since March, when the EU-Turkey agreement to stem the influx was implemented.

During the last 24 hours, 65 immigrants and refugees have arrived on the northern Aegean islands.

Boats keep coming as tensions on the islands, in particular Lesvos, have dramatically risen lately.

Monday's fire at Moria's camp was the culmination of a long string of protests by refugees over poor living conditions in overcrowded facilities and delays in the examination of asylum bids.

Under an agreement made in March, incoming refugees are not transferred to the mainland, but remain on the islands until their asylum request is assessed.

The Moria hot spot was established last year to accommodate about 1,000 people. Until Monday, it hosted more than 3,000 refugees and migrants.

According to the local fire brigade, it was the third fire which had broken out on Monday at Moria village during the tension. The first two took place on a field near the hot spot, burning 16 acres of dry grass and olive trees.

On Tuesday morning, dozens of immigrants and refugees were outside the hot spot of Moria, waiting for the space to be cleaned.

"I've been waiting here for three months and I want to leave, open the borders," said 35-year-old Zaharie from Sudan.

Biral, a 26-year-old from Eritrea, said he had been in Moria for eight months.

"I can't stand it anymore. We eat potatoes or spaghetti every day and it is not enough for everyone. We stand in the queue under the sun. Something has to be done immediately. The Afghans are fighting with the Africans. There are complaints all the time, and we need peace and security," Biral said.

One hundred unaccompanied minors staying at Moria until Monday have been transferred to the open refugee camp PIKPA, which is run by volunteers.

Boni, a 14-year-old boy from Pakistan who has been in Moria for nine months and was transferred to PIKPA with the other minors, said "Moria is a jail."

"We want to go out. We want to be interviewed for our asylum request," said 16-year-old Goni, also from Pakistan, who has been in Lesvos for eight months.

In a letter addressed to the Deputy Minister of National Defense, Dimitris Vitsas, the organization Co-existence and Communication in the Aegean asked for the permanent accommodation of minors in other facilities.

"The only solution is the immediate transfer of minors from Lesvos and their settlement to a proper environment on the mainland. We are begging you: Save these children," said the president of the organization, Stratis Pothas.
