Several of the ISIS jihadis who launched a series of coordinated terrorist attacks in Paris last November - slaughtering hundreds of innocent people - entered Europe through Hungary by posing as refugees.

Seven of the nine Islamist extremists involved in last year's attacks in Paris slipped through the country's borders by using fake Syrian passports and posing as migrants.

Hungarian security officials revealed how they had gained entry to Europe - and said some of them were also understood to have taken part in the Brussels attacks last March, which claimed 32 lives.

They were among 14 members of ISIS terror cells using Hungary as a gateway to western Europe.

The attacks in Paris on November 13 targeted the Bataclan concert hall, cafes and the national stadium, killing 130 people.

Some 368 were also injured in the attacks, 100 of them seriously.

According to Hungary's centre for counter-terrorism, it is thought ISIS set up a 'logistics hub' in the country in the Summer of 2015 at the peak of the migrant crisis, when jihadis slipped into Western Europe through Eastern Europe's Balkan routes.

Paris ISIS attacker Salah Abdeslam is believed to have played a key role in the logistics of the Paris attacks, hiring the cars and renting the safe houses for the other members of the ISIS cell.

He is understood to have made four trips to Hungary in August and October 2015 in which he picked up other terrorists linked to both the Brussels and Paris attacks.

Speaking to the Sunday Times, deputy counter-terror chief General Zsolt Bodnar said Abdelhamid Abaaoud, the Belgian-Moroccan terrorist who died after the Paris attacks, had sent a scout to 'map out' the migrant route in July 2015.
