The gruesome discovery of up to 50 decomposing bodies, believed to be those of migrants, in an abandoned truck in Austria this week was just the latest tragedy for the hundreds of thousands of people fleeing war, violence and poverty for a better life in Europe.
The grisly find came as leaders from the European Union and the western Balkans met in the Austrian capital of Vienna to discuss the worst migration crisis since World War II.
“This reminds us that we in Europe need to tackle the problem quickly and find solutions in the spirit of solidarity,” German Chancellor Angela Merkel said after the bodies were found.
“The world’s eyes are upon us.”
The pressure to find a solution is intensifying by the day. Resources are being stretched to the limit, particularly in Greece, Italy and Hungary, where most migrants first arrive before moving on to richer EU countries like Germany, France and Sweden.
As Europe struggles to cope with the influx of so many people in such a short period of time, some countries are taking an increasingly hardline stance on the problem.
Hungary and Macedonia, for example, have deployed security forces along their borders to stop the flow of men, women and children who have mostly traveled from the Middle East and North Africa.
The strategy isn't working too well.
The response to the crisis so far threatens the "soul" of Europe, Italian Foreign Minister Paolo Gentiloni told the Il Messaggero newspaper, according to Voice of America.
"On immigration Europe is in danger of displaying the worst of itself: selfishness, haphazard decision-making and rows (disputes) between member states. I am very worried. Today it is on this issue that Europe will either rediscover its soul or lose it for good," Gentiloni said.
Here are six facts and figures that will help explain the scale of the problem — and the challenges to solving it.
This is why it has been described as the worst migrant crisis since World War II: Nearly 340,000 migrants entered the European Union between January and July, according to the European Union’s border control agency Frontex.
That compares with 123,500 for the same period in 2014 and 280,000 in all of last year.
In July alone a record 107,500 migrants were detected, more than triple the number for the same month last year.
"Syrians and Afghans accounted for a lion’s share of the record number of migrants entering the EU illegally,” Frontex said.
“Most of them, fleeing instability in their home countries, initially entered Greece from Turkey.”
European immigration officials have been inundated with applications for asylum.
In the first three months of this year a total of 184,800 people requested asylum for the first time, up a staggering 86 percent on the same period last year, according to Eurostat.
The top three nationalities seeking asylum were Kosovars (48,900), Syrians (29,100) and Afghans (12,900).
Authorities are struggling to keep up. Nearly 122,000 decisions were made, of which 46 percent resulted in “a type of protection status.”
One of the most popular routes into Europe is the Mediterranean Sea. So far this year, an estimated 267,121 people have made the perilous journey from North Africa and the Middle East, according to the International Organization for Migration.
Tens of thousands of them only survived after being plucked from the ocean by rescuers patrolling the waters.
Last Saturday, Italy’s coast guard rescued more than 4,000 migrants off the coast of Libya after receiving distress calls from more than 20 boats.
The tragic fact is many migrants don’t survive the journey.
So far this year, 2,373 people — men, women and children — have died attempting to cross the Mediterranean Sea in overcrowded and unseaworthy boats, the IOM said.
That makes it the deadliest migratory route in the world, accounting for 72 percent of the 3,279 migrant deaths worldwide this year.
Many migrants die before they make it to Europe and, as the gruesome discovery of dozens of bodies in an abandoned truck in Austria shows, even after they have crossed the border.
There might be 28 countries in the European Union, but just five — Germany, Hungary, Italy, France and Sweden — took 80 percent of the asylum applications in the first three months of the year, Eurostat data shows.
Germany is taking the lion’s share. German officials have said they expect to receive 800,000 asylum applications this year — nearly double the forecast made earlier this year.
That’s more than any other EU country and way more than the 626,000 applications received by the entire EU last year.
Germany insists it can cope with the huge numbers of migrants, but it has called for a “fairer distribution” to ease pressure on the countries receiving most of them.
"This is a challenge for all of us, [but] Germany is not overwhelmed," Interior Minister Thomas de Maiziere told the BBC this month.
The influx of migrants is fueling tensions along national borders and has sparked violence and protests in towns where migrants are being housed in tents, gymnasiums and disused hotels.
That is about twice the number during the same period in 2014.
There have also been protests as a small but vocal minority expresses their disapproval at the arrival of so many migrants.
But German Chancellor Angela Merkel said there would be “no tolerance” for anti-migrant violence.
Elsewhere in Europe, there have been disturbing scenes along Macedonia’s southern border with Greece, where security forces have reportedly used stun grenades, tear gas and rubber bullets to stop people from entering the country.
“These are very serious allegations of excessive force by the Macedonian police firing at people seeking protection,” said Emina Cerimovic, research fellow at Human Rights Watch.
“Macedonian authorities should be protecting migrants, including children and those among them who may be fleeing war and persecution, not giving the police a green light to fire at them.”
Hungary, which is constructing a razor wire fence along its border with Serbia to stop the flow of migrants taking the increasingly popular Balkans route into the EU, is also considering deploying the army.
That would be in addition to the thousands of police it has already sent to the area.
