In the wake of the terror attacks on the Belgian city, Farage delivered a damning verdict on the self-proclaimed centre of Europe.
Speaking to Julia Hartley-Brewer, he was typically forthright in his views.
He said: "Brussels is now the Jihadi capital of Europe. We know there is a complete state of lawlessness in that city."
His primary concern is the free movement zone in the EU, adding: "This Schengen, this free movement zone is a lovely idea when everything is hunky dory, but in reality, the free movement of people has become the free movement of terrorists, criminal gangs and Kalashnikovs."
Farage was also asked about the issue of the forthcoming EU referendum, and he admitted concern as to whether or not the general public would retain their interest for the next three months.
"The negativity we hear from all the people on the front line of the Remain campaign, they keep telling us the sky will fall in – I think that’s going to bore people," he said
"We will warn people about open borders and terrorism, but our message is the sunny optimistic one, which is that we can govern ourselves, trade with the world, and I think in a very long campaign, us having optimism will help us."
With regards to his future after the referendum, Farage stressed, "if we take this opportunity great, if we don't, I doubt we'll ever get the chance again.
"If we vote to leave, we have to make sure the British government fulfils the will of the people, and UKIP's role in that will be very, very important. I made a big sacrifice to do this because I believe this country should be independent. I want to win this referendum."
