Two huge ships have arrived in Kos as part of emergency measures to ease migrant pressures on the holiday island.

The Greek government dispatched the Eleftherios Venizelos, which can hold up to 2,500 people, and a large ferry as ever-growing numbers of migrants arrive on the tiny island.

The ship is being used as a floating registration centre while the ferry is transporting hundreds of migrants to Piraeus, the port close to the Greek capital.

Pictures taken today show thousands of people queuing to board the vessels, while scores more are living on the streets of the island, which has a population of just 30,000.

An estimated 200 refugees are arriving on the island every day, after making the dangerous crossing from Turkey in dilapidated dinghies.

Families have been forced to set up tents on the island's pavements and streets, while others sleep out in the open with just trees for shelter.

Up to 5,000 migrants are on the island waiting to be processed, but the growing tension is threatening to erupt into violence.

Local authorities of Kos Town appealed to the government yesterday to send in the army, to help maintain order and to distribute aid packages.

Volunteers, who have been handing out food and water for the past weeks, insist that they are no longer able to cope with the numbers.

It is hoped the cruise liner, which has arrived at the island today and is expected to be moored for a fortnight, will act as a floating registration centre.

Kos Mayor Giorgos Kyritsis said: 'It's not going to be used as a camp. As soon as it is filled with migrants, the ship will depart and another ship will come.'

The European Union pledged today to fast-track new funding to help debt-hit Greece cope with the surge in migrants.

Brutal conditions were reported on Kos earlier this week, with a single water hose and just two toilets for over 1,000 migrants crammed into a football stadium under baking sun waiting for travel papers.

Greece is just one of the flashpoints of a migrant crisis erupting across Europe. Housing is particularly a concern, with rights activists slamming conditions for refugees in Austria and asylum seekers in Germany getting a decidedly mixed welcome.

'Today the world finds itself facing the worst refugee crisis since the Second World War,' EU Migration Commissioner Dimitris Avramopoulos told a press conference.

To the rescue: The cruise liner dispatched by the Greek government arrived in Kos today. It is planned to act as a floating registration centre for migrants stranded on the Greek island

Reducing pressure: It is hoped the cruise liner, the Eleftherios Venizelos, which has arrived at the island today, will act as a floating registration centre

Big change: The cruise liner will be a far cry from the living situation the refugee families are used to, as it comes with its own piano bar and roof-top swimming pool

Stranded: An estimated 7,000 migrants are living on the tiny Greek island, which has a population of just 30,000. Some 5,000 of these are waiting to be processed so they can continue with their journey

In response to the situation in Greece, the European Commission is fast-tracking a Greek request for 2.7 million euros ($3 million) to support UN efforts to deal with the migrants arriving on the Aegean islands, Avramopoulos said.

Greece will also soon receive a first disbursement of 30 million euros from a total of 2.4 billion euros ($2.6 billion) of funding for all 28 EU member states to cope with the flood of migrants until 2020.

The money comes as the number of people driven from their homes by conflict and crisis has topped 50 million for the first time since World War II, with Syrians hardest hit, the UN refugee agency said.

Some 124,000 refugees and migrants landed on the Greek islands during the first seven months of the year - up 750 percent from 2014, according to UN figures.

And about 102,000 people have traveled from Libya across the Mediterranean Sea to Italy so far this year - compared to 2014, when 170,000 made the trip during the entire year, the International Organization for Migration.

All new arrivals to the island must be processed and issued with papers by local police before they are able to continue with their journey.

But with an estimated 200 migrants arriving every day, from war-torn countries such as Eritrea, Sudan and Syria, the authorities are unable to keep up with the crushing demand.

Under pressure: Local authorities in Kos cannot cope with the estimated 200 people who arrive on the island every day, and there is a massive backlog waiting for documentation

A separate ship carrying migrants to Athens from Kos had to turn back after a pregnant woman suffered complications.

The ferry was able to carry on later in the day, after the woman had been treated at a hospital on the island of Kos.

It delivered 1,350 people to Piraeus, the port closest to the Greek capital, according to the website The Rhodean.

Although around 1,800 migrants who had received their papers also left the island on a boat on Wednesday night, there is still a massive backlog.

One effort to cope with the escalating demand for documentation nearly ended in disaster on Tuesday and Wednesday, when 2,000 mainly Syrian refugees were locked inside a stadium in soaring temperatures for more than 12 hours.

The crowds of people had no access to water, no food and no toilets as they queued in temperatures of up to 35 degrees Celsius.

Inside the stadium, three police clerks were struggling to register hundreds of refugees, and were forced to use fire-extinguishers to control the jostling crowd.

The office on Kos for Doctors Without Borders, the medical charity, strongly criticised the conditions in the stadium, where most refugees were sent after being evicted from makeshift camps all around the town.

'What we see now is a completely disproportionate focus on security management of these people without the relative humanitarian assistance that they need,' said Vangelis Orfanoudakis from the charity.

Near-miss: Migrants line up during a registration procedure at the national stadium today in Kos. One effort to speed the documentation process along nearly ended in disaster this week, as more than 2,000 migrants were locked inside a stadium for more than 12 hours without access to food, water or toilets

Crowds of people: Authorities in Kos have called for help from the army with distributing aid, and an extra 1,000 food packages a day

'There are just two toilets. No access to water. They now have put a water hose for all the people, the situation is really dramatic,' he said.

Authorities in Kos have called for help from the army with distributing aid, and an extra 1,000 food packages a day.

There are already army bases located on the island, but without the approval of the Greek Ministry of Defence they are unable to help.

Elsewhere in Greece, the army has already begun efforts to ease the pressure of the migrant crisis.

Military spokesman Colonel Nikolaos Fanios said troops were preparing to hand out tents to migrants camping on the outskirts of Athens, which is generally the next stop on the migrant journey.

Kos is one of several Greek islands struggling to accommodate the biggest wave of mass migration since the Second World War.

Greece has become the main gateway to Europe for tens of thousands of refugees and economic migrants, mainly Syrians fleeing war, as fighting in Libya has made the alternative route from north Africa to Italy increasingly dangerous.

Nearly 130,000 people have arrived since January on the eastern Aegean Sea islands from nearby Turkey, a 750% increase over last year.

Meanwhile scores of families from the Middle East and North Africa are crowding onto trains in Macedonia and Serbia, countries that are fast becoming a hub for illegal migration into Europe from all over the world.

Huge crowds of people have been pictured waiting on the tracks at a train station in the town of Gevgelija, on the Macedonian-Greek border, while others crowd onto buses to take them through Serbia to Hungary.

Migrant routes: The most popular migrant routes are putting extreme pressure on Europe's southern countries, such as Greece, Italy and Macedonia, which act as gateways into Europe

Desperate flight: Families are racing to cross from Macedonia, through Serbia and into Europe via Hungary, before Hungary completes its anti-migrant fence at the border on August 31

The majority have arrived via land through Bulgaria and Turkey, after fleeing war-torn nations such as Syria and Afghanistan.

African migrants coming to Macedonia and Serbia will already have made the dangerous crossing from Greece, in overcrowded and dilapidated boats run by people-smuggling gangs based in North Africa.

These desperate families are racing to cross from Macedonia, through Serbia and into Hungary before the Hungarian border forces complete a 109-mile fence designed to keep migrants from entering the country.

Slammed by human rights groups, the 13ft-high fence is set to be completed on August 31.

Construction of the fence began in earnest on August 3, with soldiers using heavy machinery to drive metal rods into the ground.

Aggressive: More than 900 soldiers are involved with the hasty construction of the fence, which has been slammed by human rights groups

Rush job: Some elements of the fence, including the razor wire to be placed on top of the barrier, is being prepared by inmates from Hungarian prisons, and people in a state work program may also be sent to help the soldiers

Work on the fence is being carried out a several different locations, with around 900 soldiers taking part in the project.

Some elements of the fence, including the razor wire to be placed on top of the barrier, is being prepared by inmates from Hungarian prisons, and people in a state work program may also be sent to help the soldiers.
