- In Greece, five new holding camps

are being built to the tune

of almost $300 million.

At the rate migrantsare crossing into Greece

from Turkey, however,

no sooner will the camps be built,

than they will be full.

The number of migrants entering Europe

is up over 300% since last year.

There are many othercamps in Greece as well.

I visited this one north of Athens,

which holds more than3,000 people from Iraq,

Afghanistan and Palestine.

This camp has been here for years

and it's really turned into kind

of its own little city.

They've got market, nice, eggplants.

Very good.

It's got all kinds ofshops and barber shop,

everything they need.

The only thing that theyreally can't get here

is a passport or a visa

to allow them to leave.

- The weakest point of the external border

is the weakest point for everybody.

And people will exploit this.

- [Chuck] Europe has a newborder force called Frontex,

which lends assistance to countries

as the number of migrantscontinues to swell.

- It is the first timethat a European agency

has or even the EU has a uniform service.

So our budget is growing.

We have a lot more responsibilities.

We are dealing with border crime.

We're becoming kind oflike the border agency

for the entire EU.

- [Chuck] With just more than1,400 employees at the moment,

Frontex is slated to hireup to 10,000 people by 2024

with the threat of terrorismbeing a key driver for growth.

- There are security issues

and you have to, at the very least,

you have to know who'scrossing the borders.

And that's the basic responsibility

of any border guardorganization, certainly Frontex.

We have to know who's coming in

so that we can check them and screen them,

and then catch potential security threats.

- The central Mediterranean sea routes

from Morocco, Tunisia and Libya

are especially worrisome,

and especially so to theItalians and the Spaniards

who have seen quite a fewterrorists come through

on boats from those territories,

along with larger, morebenevolent refugee flows

where they're camouflaging their way in.

- I decided to fly from Greece to Morocco

to get a look at thescope of this problem.

For the millions of Africans

who would love to maketheir way into Europe

for a better quality of life,

this is the narrowest pointbetween the two continents.

This is the Strait of Gibraltar.

That's the Rock of Gibraltarright back there behind me.

And it's only eight milesfrom here to Europe.

But there's an even closer way

that they could cross into Europe

and stay here in Africa

and that's by getting across this fence.

That is all that separates Africa,

Morocco in this case, from the enclave

that belongs to Spain,

which is a city called Ceuta.

This tiny Spanish city of 80,000

has been hit hard withillegal crossings this year.

At times, that number's been fomented

by the Moroccan government

as a way of punishing Spain

over disagreementsbetween the two countries.

- 9,000 people ended up in Ceuta,

which is a small place

and so most of them were sent back

but it showed again migrants being used

as basically tools, let's say,

even as weapons in a broader issue.

- [Chuck] Otman Bobois an Algerian migrant

who has already been deported

from Spain twice.

Still, he intends tokeep trying to get in.

(speaking in foreign language)

- [Interpreter] At 4:30 in the morning,

we entered the sea.

There were two guard dogsthere that smelled us.

The guards told us to stop

but we kept swimming directly to Ceuta.

- [Chuck] While he wascaught and sent back,

the fact that he can make10 times as much money

on the other side of that fence

is the reason he keeps trying.

- [Interpreter] I havea job waiting for me

in the scrapyard just over there.

A friend who I was in prisonwith is holding it for me.

I'm not afraid, never.

I'm 35 years old and I've got nothing.

It's better to die, to be killed.

35 years old with no wife.

It's crazy.

- [Chuck] But the threat ofmore terrorists infiltrating

with migrants is very real.

- In 2020, just for example,

of the 10 successful kineticattacks on the mainland,

half of them, five of them

were conducted by migrants

or people who came in as migrants.

There's some thought that at least a few

of them were sent in on purpose

by ISIS's external operations division.

- If you talk to a lot of groups here,

anybody who's comingto Europe is a refugee.

No, I'm sorry because most of the people

that come are not refugees.

They're economic migrants

and you can have specificways of dealing with them.

But there has to be a system.

You can't just open the doors

and let anybody else in.
