The EU's top official has today vowed to 'hold the line' in support of Greece as the country revealed it had stopped 24,000 people from entering the bloc after Turkey threw open its borders.

Ursula von der Leyen said the EU would provide 'all the support needed' to defend the 'Greek external border, which is also the European border'.

'Those who seek to test Europe's unity will be disappointed. We will hold the line and our unity will prevail,' the European Commission president said.

Austrian chancellor Sebastian Kurz has meanwhile accused Turkey of 'blackmail' and launching an 'attack' on the EU using migrants as leverage.

Recep Tayyip Erdogan tore up a deal to guard Europe's borders last Friday in an effort to pressure Western leaders over the conflict in Syria.

Greek border guards said some 24,000 people were stopped trying to cross the border from Turkey between Saturday night and Monday, with tear gas fired to keep the crowds back.

On Tuesday the crowds had largely moved away from official crossing points and were trying to get through by wading or sailing across the Evros/Maritsa river, which runs the entire length of the border.

Turkey says more than 100,000 migrants have crossed its border in an attempt to get to Europe, but Greece put the number of attempted crossings much lower at 24,000

Many of the migrants are now camped out along the banks of the Maritsa river which runs the length of the Greek-Turkish land border and are attempting increasingly risky crossings

Footage taken by Turkish media also revealed what appeared to be Greek coast guards firing warning shots at and attempting to capsize a migrant boat as it headed for the island of Lesbos.

European Commission President Ursula von der Leyen travelled to Greece on Tuesday along with other officials where she toured the border zone with Greek Prime Minister Kyriakos Mitsotakis.

She pledged that the EU will provide 'all the support needed' to help tackle the migration surge

'Those who seek to test Europe's unity will be disappointed. We will hold the line and our unity will prevail,' von der Leyen said.

CYPRUS BRACES AFTER TURKEY OPENED ITS BORDERS Cyprus' president said Tuesday his country fears a migratory influx after Ankara allowed refugees to leave for the European Union and people massed on the Turkish-Greek border. The Mediterranean island of Cyprus is split between the Republic of Cyprus, an EU member state, and a breakaway Turkish entity in the north, recognised only by Ankara. 'With what is happening at the Greek border with the migrant flows from Turkey, and Cyprus being first in the number of asylum seekers... (relative to) population... we are certainly concerned,' Republic of Cyprus President Nicos Anastasiades told reporters. 'We want to evaluate what steps we can take so that, without bypassing human suffering... we will be able to prevent efforts to alter the demographic character of the country,' he added. The Republic of Cyprus says it is on the frontline of the Mediterranean migration route with the highest number of first time asylum seekers per capita. 'There has been a 320 per cent increase over the last two years in the flow of refugees' into Cyprus, taking the proportion of refugees to 3.5 percent of the population, government spokesperson Kyriacos Koushos told reporters on Tuesday. Noting that the borders of Cyprus and fellow EU member states Greece, Italy and Malta are especially exposed, he urged Brussels to 'finally take serious decisions on the issue of migration, regarding refugees from countries with unstable conditions, but also economic migrants.' Koushos said that European Council President Charles Michel is to visit Cyprus to discuss the issue. Anastasiades held a telephone conversation with Greek Prime Minister Kyriakos Mitsotakis on Tuesday about the migrant situation. Turkey has had troops stationed in the north of Cyprus since 1974 when it invaded and occupied a third of the Mediterranean island in response to a coup sponsored by the military junta then ruling Greece. While the Republic of Cyprus has an increasingly high number of refugees per capita, it has not seen the massive aggregate inflow of migrants experienced by Turkey and Greece. Advertisement

Turkey has given a green light to refugees and migrants on its territory, many of them displaced Syrians, to leave for the European Union, in defiance of a 2016 deal to keep them in.

Kurz accused Turkish President Recep Tayyip Erdogan of luring people with 'false promises' and transporting them to the Greek border - from where they are seeking to enter Europe - using them as a 'weapon' to pressure the EU.

Kurz said it was a 'test' for the EU to see whether it can protect its outer borders, saying Austria stood ready to support Greece and any other countries which may face an 'onslaught'.

'I can guarantee you one thing: if the outer borders of the EU don't work, then Europe without (inner) borders is history,' he said.

'We must together make sure that year 2015 doesn't repeat itself,' he added, referring to a surge in people entering the EU to seek asylum five years ago.

Thousands of migrants searched for ways to cross Greece's land border on Tuesday, days after Turkey made good on a longtime threat to open its borders for those seeking to cross illegally into Europe.

Many of those hoping to enter Greece were trying their luck by wading or rowing across the Evros River that runs along most of the length of the Turkish frontier.

Greek authorities said the main pressure on the border Tuesday had moved from the official crossing to points farther south along the river. Authorities said they thwarted an attempt by about 1,000 people overnight to make their way across the Evros wetland area, at the southern end of the border.

Top EU officials were accompanying Greek Prime Minister Kyriakos Mitsotakis Tuesday on a tour of the area around the land border to assess the situation that Greece has described as an asymmetric threat against its national security.

Mr Mitsotakis had earlier called for 'strong' support from the EU in tackling the problem, ahead of a meeting with European leaders.

The EU has largely been on the sidelines of the issue but on Monday von der Leyen said: 'The challenge that Greece is facing right now is a European challenge.'

Some 24,203 people were stopped from crossing the border from Turkey between Saturday and Monday night, according to figures from the Greek government, which has sent troops and police to reinforce its border areas.

Security forces have fired tear gas to attempt to repel the migrants in recent days.

Turkey announced Thursday it was easing restrictions on those wishing to cross into Europe, leading a wave of thousands of people to mass along its western frontier.

The movement appeared well organized, with buses, minibuses and cars provided in Istanbul to ferry people to the border, a roughly three to four hour drive away.

Having been turned away from official border crossing points, migrants have now spread out along the Evros river which runs the length of the border and are trying to cross. Greek border guards say they turned back 1,000 people who tried to cross the Evros wetlands overnight

The vast majority appeared to be Afghans, along with people from a wide variety of countries, including Iran, Iraq, Bangladesh and Syria.

Turkey's announcement upended its previous policy of containing refugees and other migrants under an agreement with the European Union, in which the EU would provide billions in funding for the care of refugees within Turkey.

Turkish President Recep Tayyip Erdogan, whose country hosts more than 3.5 million Syrian refugees, has long maintained the EU has not lived up to its side of the deal, and has demanded more support from Europe.

He says his country is facing an imminent and dramatic new influx of refugees from the war in Syria, where growing clashes between Turkish and Syrian troops has raised alarm.

However, Turkey's border with Syria remains shut and there has been no indication he might open it.

Greek authorities said that in the 24 hours between Monday and Tuesday morning, they had prevented a total of 5,183 people from entering Greece, and arrested 45 people, mostly from Afghanistan, Pakistan, Morocco and Bangladesh.

Greece has made clear its borders are shut. It has sent military and police reinforcements to the area, which have used tear gas and water cannon to repel mass attempts by migrants to cross into the country.

Authorities have also set up cordons of police and army checks on and near the border, arresting those who managed to make it through.

On Tuesday morning, two men - one from Mali and one from Afghanistan - were seen being arrested by Greek authorities shortly after crossing the border, and being loaded into a van with about 20 more people, from Somalia, Afghanistan, Bangladesh and Iraq.

Migrants have also been trying to reach Greece by making the short but often perilous sea crossing to islands from the nearby Turkish coast.

A young boy died on Monday after the dinghy he was in capsized off the coast of the island of Lesbos. The other 47 people in the boat were rescued.

On Monday night, Greek authorities said they had stopped more than 24,000 attempted illegal crossings at the land border with Turkey since early Saturday, and arrested 183 people - very few of whom were Syrians.

European countries have largely backed Greece. On Monday, Erdogan said Western leaders were calling him and urging him to reverse the border opening.

'It's done, the gates are open now. You will have your share of this burden now,' he said he told them.

Soon 'the number of people going to the border will be expressed in millions,' he said.

Top EU officials, including European Commission President Ursula von der Leyen, were to join Mitsotakis, the Greek prime minister who was visiting the border area Tuesday.

During his visit, Mitsotakis was briefed that Turkish authorities were busing migrants to specific areas of the border 'in order to increase the pressure on the Greek border,' a government official said.

The official spoke on condition of anonymity because he was not authorized to speak on the record.

Greek authorities have also said Turkish authorities have fired tear gas at the Greek border and Greek forces guarding it, and have provided video footage of tear gas being fired into Greece.
